Power Plant high pressure isolation valve choices
Considering isolation valves on the higher pressure systems (HP) essentially there are two choices. The first one, the wedge gate valve, has risen in popularity due to the drive to reduce costs. It offers a ‘one time’ sealing solution due to the wedging action between the plug and the seat. However, these valves should be avoided on steam plants where temperature changes potentially result in thermal binding of the wedge and locking of the valve in the closed position. The best solution for power plants is the parallel slide valve, invented by Hopkinson in 1881. Compared to the wedge gate valve; all the components in a parallel slide valve are free to move no matter what the temperature. This means that, as the valve heats and cools, seat integrity is maintained without any thermal locking. The valve has a rising stem but, unlike the wedge gate valve, it is positioned seated, meaning there is no additional force required to seat or un-seat the valve.

At Turow, Poland Derakane replaces borosilicate glass
The FGD (Flue gas desulfurization) unit operates at a temperature of 160 F (70C) under normal conditions. However, during the construction period, two of the four units were not operative and ran in the bypass mode. During the by-pass operation one of the units ran for two years at temperatures up to 320F (160 C). The previous chimney liners were constructed of borosilicate blocks which needed to be replaced due to the wet circumstances and the huge swings in temperature 70 – 320 F (20 – 160 C). Each of the four units consisted of a chimney liner 17 feet (5.3 m) in diameter and 395 feet (120 m) tall. In addition, there was a total of 1100 feet (330 m) of ductwork with the same diameter. FRP fabricated with Derakane 470HT was selected for this project due to its chemical resistance to the wet flue gas and its ability to manage the huge swings in temperature up to and beyond 320F (160 C).

Older review of India particulate and FGD options
This article is several years old but has some current value. Precip upgrades are needed. For example; NTPC Rihand, whose performance is good (gross efficiency of 36 per cent), is upgrading its 25-year-old ESP to meet PM norms of 50 mg/ Nm3. It is installing advanced moving electrode electrostatic precipitator technology in two fields (the remaining four fields in the middle will remain fixed-electrode type) of the ESP. This technology is expected to reduce emissions from around 400-500 mg/ Nm3 to 50 mg/ Nm3. Relative to FGD Major power equipment manufacturing firms have signed patent agreements for SO2 emission control technologies. Thermax has signed partnership with Marsulex, ISGEC Heavy Engineering Company Pvt Ltd with Amec Foster Wheeler, and Bharat Heavy Electricals Ltd. (BHEL) with Mitsubishi Hitachi etc. Domestic companies like Transparent Technologies Pvt Ltd have developed indigenous technologies for SOx, however, they have limited experience of larger installations, NOx and PM control technology and are mostly indigenous.

High Chlorine coals are less costly and can create a byproduct
The advantages of using high chlorine coals are the lower cost and the ability to produce a byproduct. This article points out that Illinois coals with 0.2% chlorine content are being burned in many units without extreme corrosion. In fact, it is hard to draw a direct correlation between corrosion and chlorine content. Some coals with 0.3 % coal are being successfully utilized. The conclusion is that there are multiple factors creating the corrosion. Steps such as more even fuel combustion can be more important than chlorine content.

China developing new flyash uses as building industry slows
China’s coal-fired power plants produce about 600 million tons fly ash annually, which has caused severe economic and environmental problems. This paper first describes briefly the production and utilization status of coal fly ash in China. Then it analyzes the main challenges to the fly ash utilization in China due to the conflict between the huge amount of production of fly ash and the depressed consumption of fly ash, as well as the increasing driving forces in environmental protection. Subsequently, the new developments of fly ash utilization in China, including valuable elements extraction, geopolymer production, fly ash-based ceramics synthesis and soil desertification control are introduced in detail. CFA can mix with cement, gypsum and clay, etc. to produce autoclaved aerated concrete blocks. Because no high temperature is required. This technique reduces air pollution and decreases energy consumption, so the above utilization ways are very popular in China.

Dense slurry key to ZLD at Hungarian Power Plant
The U.S. Environmental Protection Agency identified biological treatment as the baseline treatment technology for FGD wastewater in the ELGs. However, it is becoming evident that bioreactors exhibit high capital and operating costs, occupy significant space, and are sensitive to changes in temperature and pH. Dense slurry ash management can sequester large quantities of FGD wastewater along with the contained contaminants through hydration, encapsulation, and entrainment for a fraction of the cost of traditional treatment. By using dense slurry sequestration of FGD wastewater, off-site discharge of effluent can be avoided altogether. Dense slurry was employed at (among other plants) the Matra Power Plant near Budapest, Hungary, and this technology played a key role in helping the plant achieve zero liquid discharge (ZLD). The Matra project is summarized and data are presented that show how the technology helped the plant achieve ZLD and other environmental objectives. Note: As of 2001, NAES Corp is a Division of Itochu

UK is importing ash and taking global view
In 2017 the UK generated only 1 million tons of ash, recovered 0.5 million from landfills and imported 254,000 tons, so demand exceeds supply and this gap will increase with more coal plant retirements. From October 2016, the UK Quality Ash Association (UKQAA) started to accept members from overseas. As the market for quality ash continues to grow, UKQAA believes the importation of ash will have an important role to play in the future. While the main role is to protect and maintain UK production and supply, the transition away from coal-fired power over the next five years will have an impact on supply if UKQAA doesn’t intervene. Importation from around the world has huge potential and the association believes its technical advice, guidance, and expertise can help to safeguard future supplies of quality ash – a material that continues to enjoy considerable demand from the construction industry, and for very good reason.

SEFA upgrades flyash and eliminates an environmental challenge
SEFA has successfully demonstrated the viability of STAR® Technology through commercialization at three STAR® facilities. The most recent STAR® Plant at the Winyah Power Station has the ability to process 100% ash reclaimed from ponds. The waste heat generated from the STAR® Process is used to dry the pond ash thus making the entire plant a self-sustaining closed loop system. Further, the plant can switch at a moment’s notice from the reclaimed ash to 100% dry ash produced at the power plant, or any blend of both. This flexibility allows full load operation at all times without any dependence on operation of the power generation plant now or in the future. This unique independence is particularly important as the supply of fly ash for the construction industry continues to dwindle as more coal fired generation is taken off line. At the same time the market for high quality fly ash continues to grow. Utilizing reclaimed ash from ponds and landfills will provided continuous feed material and ensures uninterrupted supply for customers.

Coal fired power in the U.S. and Europe shaped by regulations
Tony Licata provided a good summary of the impact of environmental regulations on coal fired power. He observes that the economic pressures of compliance with the MATS rule and the price of natural gas available for power generation have directly resulted in the closure of more than 30 GW of coal-fired capacity. As a result, there have been regional shortages of fly ash sold to the cement industry. This shortage has caused fly ash to be imported from China in some cases. However, certain high-uranium coal deposits in China produce fly ash that is too radioactive for reuse.

United States Imports and Exports are significant portions of Apparent Consumption. Magnesia markets tend to be worldwide. China in particular is a major producer and consumer of magnesia products. USGS Data show that China has exported large quantities of magnesium oxide (MgO) to the United States. Magnesia is used in several Markets, and global supply and demand is driven by global product requirements in those markets. Events in China since 2016 have reduced both imports and exports to China. Martin Marietta Magnesia Specialties is vertically integrated. This means an unusual level of control over raw materials such as dolomitic lime from its plant in Woodville OH.

Wet booster fans evaporate small droplets leaving the FGD scrubber
Alden Research Laboratory performed a study in 2012 into the environmental benefits of using wet booster fans, considering that these heat up the treated flue gas by 3 to 5 degrees C. The study included both thermodynamic calculations and physical tests using a laboratory scale model. The study showed that, at nominal unit load, (a) the booster fans will have the capacity to evaporate small diameter droplets contained in the wet gas including all of the water from the fan wash cycle and (b) raise the flue gas temperature sufficiently to enable the thermally insulated, Pennguard lined chimneys to maintain the flue gas temperature just above the water dewpoint, effectively eliminating condensate formation in the wet stacks. A properly designed liquid collection system in the outlet ducts and the chimney breeching will still be needed, to collect bigger droplets that may not have enough time to evaporate.

This study by Sargent & Lundy provides methods to determine costs of DSI for acid gas removal. The sorbent requirement is a function of particle size, particulate control device, and other factors. 2016 cost factors are utilized. Based on commercial testing, removal efficiencies with DSI are limited by the particulate capture device employed. Trona, when captured in an ESP, typically removes 40 to 50% of SO2 without an increase in particulate emissions, whereas hydrated lime may remove an even lower percentage of SO2. A baghouse used with sodium-based sorbents generally achieves a higher SO2 removal efficiency (70 to 90%) than that of an ESP. DSI technology, however, should not be applied to fuels with sulfur content greater than 2 lb SO2/MMBtu.

IAC Capabilities including DSI
This analysis reviews the various different sorbents and their effectivenesss on specific pollutants such as SO2, HCl, and mercury. IAC has a testing fleet to determine the correct sorbent and amount which will be needed with the DSI approach as opposed to more capital intensive options. With DSI the reagent cost is a more significant percentage of the total, so precisely predicting the reagent needs is very valuable. Various construction capabilities of large filters and transload systems are also covered.

IAC rebuild of RA filter system for coal fired boiler
IAC evaluated a baghouse rebuild project to review a 16-module reverse air structural baghouse. The original scope of the inspection was to evaluate the baghouse for needed repairs due to concerns over corrosion that had taken place over the years, as well as overall baghouse performance. This baghouse collects fly ash off of the plant's coal-fired boilers, which are used to generate steam for the needs of the plant. A detailed inspection report was generated and sent to the customer. The report included a list of recommendations for a scope of repair work. A substantial portion of these recommendations included the replacement of numerous dampers on the baghouse, as well as the reverse air ductwork. Follow-up meetings were held at the plant to discuss various option for upgrading the baghouse equipment or possible converting it to a pulse-jet. The customer reviewed our recommendations and focused on the damper and duct repair as items to get approved for a baghouse rebuild project. Several months of internal discussions within the plant took place to further define the project. IAC provided budgetary equipment and labor pricing. IAC went through the documentation process with the customer to become an official “approved contractor”. The insurance and safety requirements were substantial. IAC was certified as an approved contractor. IAC provided all supervision, safety management, labor, tools, crane, forklifts, scaffolding, and materials. IAC's wholly-owned construction subsidiary, Adelphi Construction LC, provided all project installation manpower, including project manager, shift supervisors, safety manager, foreman, welders, pipefitters, rigger, firewatch, helpers, and confined space attendants.

$6 Billion Market for NOx Control Consumables
In 2019 stationary sources will spend $2 billion for catalysts and $4 billion for treatment chemicals to reduce NOx. This is the latest forecast in N035 NOx Control World Market. The largest purchasing segment will be coal fired boilers. This segment is shifting geographically as India is retrofitting a number of its boilers. The retrofit market in China has leveled off since a very large catalyst manufacturing industry was created. The U.S. coal fired NOx market will remain flat. The EU will show a modest gain. Stricter EU-wide standards for emissions of nitrogen oxides (NOx) will have to be met by 2021. Other markets are smaller than the coal fired power market. The gas turbine market continues to grow. This includes oxidation catalysts as well as SCR catalysts. Waste to energy plants are being built everywhere but the U.S. There are various requirements for Nox control in most industries with combustion processes. There are a number of catalyst suppliers. Improvements in technology include the combination oxidation and SCR catalyst supplied by Cormetech. The catalytic filter is a new development which could substantially affect the market. Dürr supplies Catalytic Candle Filters (CCF). The catalytically coated filter candles can withstand temperatures of up to 716° F, simultaneously remove dust, sulfur dioxides (Sox), and nitrogen dioxides (Nox) from the exhaust air. A number of biomass and glass plants have incorporated this technology in Europe and the U.S. Glass producer Libbey is the first manufacturer to use the new exhaust air purification technology in its plant in Beijing. There are a few major companies providing the Nox reagents. Yara is unusual in that it supplies SNCR systems as well as reagents. Yara is one of the largest producers in the world of ammonia and urea, with one third of the ammonia traded in the world being supplied by Yara. The company ships ammonia and urea around the world to SCR and SNCR customers via a network of 30 plants and 200 terminals and warehouses.

Constellation Energy’s 340-MW Wagner Unit 3 with SCR, tubular air preheater and cold side ESP and 130-MW Unit 2 with Ljungstrom air preheater and cold side ESP participated in Solvay Chemicals testing of Trona and sodium bicarbonate injection for SO2, SO3, NOx and mercury reduction. Industrial Accessories Company (IAC) provided the rigs, injection lances and test management. The required SO2 removal rate was 30 to 50 percent. Both units use activated carbon (PAC) injection for mercury control. The units fire CAPP coal (0.83 percent sulfur) or a blend of CAPP and PRB. Youngen Kong and Stan Carpenter of Solvay Chemicals, Salil Bose and Matthew McMillian of Constellation Energy, and Pramodh Nijhawan of IAC reported at Power-Gen International 2009 that Trona was able to meet the SO2 removal targets for various fuel types at feed rates between 1.1 and 2 NSR. A higher SO2 removal rate was obtained with sodium bicarbonate. ESP performance was enhanced by Trona (with no PAC injection) and NSR 1.1, which reduces SO2 by 29 percent. Around 10 percent NOx was also removed (a bonus) with both sorbents. For Unit 2, mercury removal increased from 82 to 90 percent with Trona injection alone (NSR 1.1). For Unit 3, up to 80 percent of the mercury was removed by PAC without Trona. Over 90 percent mercury removal was realized by PAC with Trona injection (NSR=0.1). The positive effect of sodium bicarbonate on mercury removal was also demonstrated and is comparable to Trona.

Dynegy SDA installation at Baldwin is permitted for new wastewater discharges
The subject facility has applied for a renewed NPDES permit which includes modifications that necessitate an antidegradation assessment. New wastewater discharges will be created as the result of the construction and operation of new dry flue gas desulfurization systems (Spray Dryer Absorbers or SDAs) at all three units at the complex. The installation of these systems was required by the terms and conditions of a 2005 Consent Decree between Dynegy, the state of Illinois, USEPA, and the U.S. Department of Justice. Construction of the Unit 3 SDA system and baghouse has been completed and they were put into service prior to December 31, 2010. The Unit 1 SDA system and baghouse were placed into service by December 31, 2011. The Unit 2 SDA system and baghouse were placed into service by December 31, 2012. The new discharges from these systems would consist of sump discharges, air compressor noncontact cooling waters, and miscellaneous floor and storm drainage waters. Dynegy is requesting authorization to discharge these wastewaters to the existing bottom ash pond system and include these discharges as contributory wastewater streams to Outfall 001. Sump discharges are not expected to occur more than once per week with each discharge lasting approximately five minutes. Based on the current operation of the Unit 3 sumps (projected discharge of 0.127 MG/year), it is expected that sump discharges for all units would contribute 0.38 MG/year of flow to the ash pond. Air compressor noncontact cooling waters from the new SDA systems (6.5 MGD) and miscellaneous floor and storm drainage waters would be received by the cooling pond and would be potentially discharged from Outfall 002 during overflow conditions

Water treatment and cooling applications for power plants
Plant operators need a durable pump technology that is able to dose a precise volume of water treatment chemical, while maintaining a high level of operational reliability. This is one reason why hydraulic diaphragm metering pumps are preferred for a majority of water treatment applications in power plants. The pump’s ability to survive system upset conditions helps keep the overall plant infrastructure operating reliably, all while dosing the exact amount of chemical needed to keep operations running efficiently. Space in any plant is valuable, so operators prefer pumps with small footprints. Disinfection - is accomplished by dosing specific quantities of high-concentration sodium hypochlorite (bleach). When sodium hypochlorite comes in contact with bacteria, it oxidizes molecules in the cells of the germs and kills them. Even though this simple but harsh chemical has been used for more than a hundred years, it is prone to causing problems for pumps by “offgassing.” To solve this issue, the pumps used to deliver it must be able to pass the gas bubbles through without locking or clogging the pump.

Disinfection, pH adjustment are ways to facilitate greater water reuse in power plants
The effective management of water and wastewater investments can save power plants 1 to 2 percent annually, which adds up to millions of dollars each year. While these benefits may never equal the financial advantages of once-through cooling processes, they do enable power plants to use significantly less water. The criteria for selecting metering pumps typically includes flow rates, pressures and corrosion resistance (depending on what chemicals are pumped). Although plant operators and the engineering, procurement and construction (EPC) firms that serve them have multiple options for pumping infrastructure, the most popular choices usually involve diaphragm or rotary gear pumps.

MHI facilitating the opportunity to purchase CFT Products across Divisions
The company is targeting 2018 sales of $ $37 billion rising to $45 billion in 2020……. Under its “Shared Technology Framework,” MHI Group is striving to strengthen its technological and marketing infrastructures, optimize the value chain across the Group (including procurement), and reinforce the competitiveness of its businesses in the medium-to-long term. MHI Group handles a greater variety of products than its competitors, and in order to turn this product diversity into competitiveness, it is promoting group-wide technology and knowledge sharing in product development. Applying cutting-edge technology from gas turbine development to numerous other products, such as compressors, centrifugal chillers, and turbochargers, is one example of what it is doing to realize conglomerate synergies by technology and knowledge sharing. Combust, flow and treat (CFT) suppliers therefore have the opportunity to also understand the group-wide opportunities and offer packages covering the gamut of opportunities. CFT opportunities are mainly in the following two of three main divisions----- POWER SYSTEMS: Intelligent Transport Systems gas and steam power generation systems, nuclear power plant equipment (light-water reactors/nuclear fuel cycle & advanced solutions), wind power generators, aero engines, compressors, marine machinery.-------- Overview of Fiscal 2017----------- Having been hit by global market factors such as the acceleration of the shift to low-carbon approaches and the switch to renewable energy, coal-fired power plants saw a significant decline, and order volumes for gas turbine combined cycle (GTCC) systems also fell considerably. As a result, consolidated orders received decreased year on year, to ¥1,437.5 billion. Consolidated net sales rose year on year to ¥1,493.9 billion, driven by steady progress in work-related to orders for gas and steam power generations, as well as increases in aero engines. Although there were improvements in the profitability of the gas and steam power generations, aftersales service, due to such factors as the decline in nuclear power plant equipment, operating income was flat year on year at ¥108.9 billion. ------ INDUSTRIAL: Metal machinery, environmental systems, paper converting machinery, mechatronics systems, ITS, material handling equipment, engines, turbochargers, air-conditioning & refrigeration systems, automotive thermal systems, machine tools, commercial ships, transportation systems, and chemical plants.------------- In addition to increases in metals machinery on the back of strong infrastructure investment, orders grew for turbochargers, material handling equipment, air-conditioning & refrigeration systems, and other items due to economic expansion, primarily in developed countries. Consequently, consolidated orders received rose year on year to ¥1,711.3 billion. Consolidated net sales exceeded the level of the previous fiscal year and rose to ¥1,898.9 billion, driven by increases in material handling equipment and turbochargers, for which orders were strong, and in commercial ships.----- EXAMPLES of CFT OPPORTUNITIES: Flue gas desulfurization, waste-to-energy, geothermal, CO2 recovery, marine scrubbers, sinter plant waste heat recovery, gas turbine combined cycle plants, coal-fired boilers---- ENERGY EFFICIENCY: The company is focused on improving energy efficiency with data analytics and remote monitoring. It is fostering cross divisional projects.

Cement Kiln Dust for SO2 removal
From 10 to 12 million tons of cement kiln dust accumulates annually at domestic cement plants. This finely divided dust is emitted from cement kilns to prevent the buildup of excessive salts in the cement product. If separated into its valuable components, waste cement kiln dust could become a significant source of potassium and a raw material for making cement. This article does not include the use of this dust for SO2 removal from coal-fired boilers, but potassium is very reactive and would be a good reagent. One question is its use in direct sorbent injection or DSI. There is widespread use of drinking water plant lime sludge as an FGD reagent. So other alternatives should also be explored. The use would be primarily where a small boiler is near a source or where multiple sources can be included so that enough reagent for a large application is available.

Biological Treatment or ZLD for FGD Wastewater
The Biological treatment process is perceived as the low-cost option to FGD treatment and the Zero Liquid Discharge process is perceived to be more expensive from a CAPEX and OPEX standpoint. While this is true, the difference is not as much as has been presented within the market by various engineering firms. In addition, there are options for achieving ZLD while reducing the costs associated with this alternative. Burns & McDonnell has postulated that the cost of biological treatment plants and ZLD plants are closely competitive up to 200 GPM whereas CH2M indicates the installed cost of ZLD to be three times that of Biological treatment. The equipment costs and estimated installation costs of the ZLD system generated by Aquatech paint a much more positive depiction of the relative installed costs of ZLD compared to Biological treatment.

Jim Bridger will require new pond liner
The PacifiCorp Jim Bridger Power Plant is a coal-fueled steam-electric operation with four operating units having a total generating capacity of 2.12 GW, and is located approximately nine miles northeast of Point of Rocks, Wyoming. . FGD Pond 2 is a zero discharge facility and generally evaporates water at the same rate it is disposed of in this pond. It does not have a spillway, or outlet structure. The inlet structure consists of two, 10-inch diameter HDPE pipelines which can discharge at various points along the southern side of the pond. Seepage from the current FGD Pond 2 has created a groundwater plume beneath the general area of the disposal ponds (FGD Ponds 1 and 2). This plume is presently controlled by a series of groundwater pump back wells which discharge the pumped water back into FGD Pond 2. The FGD Pond 2 does not meet the requirements of §257.71 – Liner design criteria for existing CCR surface impoundments, due to absence of an installed geomembrane liner and compacted clay soil liner. The Rule states that existing CCR surface impoundments are considered unlined if “the owner or operator of the CCR unit fails to document whether the CCR unit was constructed with a liner that meets the requirements of paragraphs (a)(1)(i), (ii), or (iii).”

HVOF Coating Case Study for Power Plant Process Control Ball Valve Applications
This is a case study of the failure of the coating on an on-off metal-seated ball valve (MSBV) used in supercritical steam lines in a power plant. The valves are exposed to rapid high-pressure and -temperature variations resulting in cracking and cohesive failure of the high velocity oxygen fuel (HVOF) 80/20 Cr3C2-NiCr coating. It was found that carbide precipitation is a major factor causing embrittlement of the coating.

Under the Proposed Clean Power Plan, Natural Gas, then Renewables, Gain Generation Share
In June 2014, EPA issued its proposed Clean Power Plan to regulate CO2 emissions from existing power plants. In May 2015, the Energy Information Administration (EIA) issued an analysis of the impacts of the proposed rule, along with this summary. According to EIA’s analysis, the main compliance strategy will be to increase natural gas-fired generation to displace coal-fired generation. Later, after 2020, as more wind and solar capacity are added, renewable generation will also surpass coal-fired generation.

MACT Compliance Options, by Pat Mongoven, Mississippi Lime, HTH 5-7-15
DSI with hydrated lime can allow SO2 & HCl reduction for both industrial boilers and cement manufacturers. Depending on the application and the facilities goals, a High Reactivity Hydrate may allow better removal or lower costs. In cement scrubber towers, DSI gave comparable removal rates to feeding a liquid slurry of hydrated lime directly to the scrubber tower.

Coal to Natural Gas Electric Utilities Repowering: Consequences for Valve Usage and Replacement
US power generating plants are converting from coal to other fuels in large numbers. In some cases the existing infrastructure is (to the extent possible) retained, with only the combustible material being altered. In the “middle” are plants that "repower" by using an existing turbine to run on steam from a heat recovery steam generator (HRSG) that draws (recycles) exhaust heat from a new gas turbine, together forming a combined cycle. At the other end of the scale are newly constructed power plants, which are predominantly gas-fueled. Each of these three repowering alternatives requires a different quantity of new valves, often of varying types.

The majority of coal-fired Part 75 utilities in the United States are now using real time continuous Mercury Vapor monitors. ThermoFisher Scientific has sold more than 450 Mercury CEMS and the majority are installed and operational. These CEM Systems are true real-time monitors designed to comply with the stringent data availability criteria required by Part 75. In defiance of the D.C. Court’s vacature of the Clear Air Mercury Rule (CAMR), many states are moving forward with the requirement of continuous Mercury emissions monitoring systems. Since 1993, all thermal power plants subject to the Part 75 Acid Rain Regulations have been required to continuous monitor for the regulated emissions, SO2, NOx, and CO2. Continuous monitoring of Mercury emissions is also expected to be the most accepted monitoring method for obtaining reliable real-time Mercury emissions. The test results at all Mercury emissions evaluation sites have shown that Mercury concentration variability far exceeds that of other regulated criteria pollutants. Multiple types of “routine operational events” occur during normal boiler operation and often trigger dramatic changes in the concentrations of both Elemental and Oxidized Mercury.

Measuring Ammonia Slip from Post Combustion NOx Reduction Systems
In many facilities there may be room for process improvement that could reduce operating costs or provide revenue enhancement opportunities. Operating SNCR or SCR technology closer to its limit offers these benefits but increases the risk of high ammonia slip. The risk could be abated with the use of ammonia monitoring technology. But, except for gas-fired plants, continuous ammonia slip monitoring technologies have not been available at a practical price to facilitate these cost-saving or revenue enhancing improvements. Conditions that exist in high dust, high temperature, high NOx and/or high SO2 environments make most analyzer methods of continuously measuring ammonia unsuitable for application to coal plants. An overview of the technologies available for measuring ammonia in the high dust region downstream of a Nox reduction system and the status of their development is provided.

Treatment Chemical Case Studies by Bruce Keiser, Nalco. - Hot Topic Hour April 10, 2014
Nalco offers chemicals to solve the mercury emission problem for coal-fired boilers. One chemical is designed to inject in the boiler, another is injected in the scrubber and a third in the wastewater. The chemical quantities can be varied in order to compensate for process variables. For example the SCR does a better job of oxidizing mercury when the catalyst is new than later in the campaign. As the oxidation potential deteriorates the quantity of chemicals can be increased.

Chemtura can supply bromine as calcium bromide or in many other forms. The company works with clients from inception through continuing operational support. Setting up calcium bromide systems is relatively easy but there is no reason to over-design and invest more than necessary or to under-design and create operational problems. Chemtura is conducting tests which show the impact of bromine in the gas and scrubbing liquor on the materials with which it may come in contact. The quantity of bromine added can vary to compensate for changes in the process e.g., changes in fuels or deterioration of the catalyst. Since activated carbon is quite expensive it makes sense to utilize bromine with the fuel to supplement the carbon under upset conditions.

Bromine can accumulate in the scrubber recycle. Confirmation of the accumulation was determined in a study at Lower Colorado River Authority (LCRA). John Grocki advised the attendees that there are big variations even between units at the same plant. There is a range of concentrations which can be of concern. Bromine and Chlorine cannot be treated the same and the combination has a different impact than either one independently. So whether there will be corrosion and which material is best to protect against it is based on the concentrations of both halogens. In addition to the scrubber itself, the injection of halogens in the fuel can have impacts on the air heater and ductwork.

Extensive CDS Experience Already Gained in U.S
Lime and hydrated lime are widely available to meet the demands of FGT applications in the U.S. power industry. Lime-based CDS technologies have become popular options to achieve very high removals of multiple pollutants produced from solid fossil fuel-fired electricity generating units. Four lime-based CDS technologies have been installed in 12 PC boilers and 12 CFB boilers. Constructions are underway at 15 PC boilers. These technologies are applied to units with sizes ranging from 58 to 690 MW. Data obtained from AES Greenidge and Sandow Stations showed that the emission limits of Hg, filterable particulate, and HCl mandated under the Mercury and Air Toxics Standards were met. CDS is capable of handling solid fuels with various sulfur contents. CDS is capable of handling wide swing load. Multiple CDS reactor vessels can be placed in parallel to process flue gases from larger units

Spray Dryer FGD at TEP Springerville
The dry FGD system for each unit comprises three spray dryer absorbers (SDA) with rotary atomizers and a reverse-air fabric filter. The Springerville Station receives high-calcium pebble lime via rail, and a pneumatic system transports the lime to a day bin located at each unit. Horizontal ball mill slakers convert the pebble lime to lime slurry, which is combined with a slurry of recycled material from the fabric filter just prior to being fed to the rotary atomizer. When the units were constructed, the dry FGD systems were built with a partial bypass, the result of which is that 75% of the flue gas is treated in the spray dryers and the bypassed flue gas is recombined with the scrubbed stream before entering the fabric filter. TEP, with S&L as Owner’s Engineer, implemented the following modifications to reduce NOX and SO2 emissions: • Installation of low-NOX burners and overfire air (NOX). • Installation of a fourth spray dryer and elimination of the flue gas bypass (SO2).

Advatech Designs Zero Liquid Discharge Systems As Well As Scrubbers
Advatech is a joint venture between URS and Mitsubishi. They have sold many scrubber systems in the U.S. Mitsubishi is the largest scrubber supplier world wide. They are now emphasizing their water management abilities including zero liquid discharge. Advatech Water Management: As concerns mount over the quality and quantity of our water supply, regulatory limits on water usage and discharge grow more stringent. In many instances, water usage brings with it a significant expense, and going to Zero Liquid Discharge (ZLD) is either a necessity or an expected near-term requirement. ADVATECH has designed wet FGD systems for chloride concentrations up to 50,000 ppm so that the only source of purge is the free moisture in the disposal-grade gypsum. However, this approach can incur a hefty cost in the form of materials of construction and decreased limestone reactivity. To minimize cost, we have been at the forefront in developing low-capital technologies capable of eliminating liquid discharge from wet FGD while maintaining chloride levels in a reasonable range, all this without the need for an expensive and complicated wastewater treatment process.

Altech MIR 9000 Capturing Market Share for HCl Measurement
Here are recent CEMS orders received by Altech: Altech will provide a dilution system for SO2 and CO2 at a milling operation in Western U.S. The system will comply with 40CFR60. Altech will replace the CEMS at a utility in the Eastern U.S. The system will measure NOx, O2, and opacity from two oil-fired boilers. The unit will be 40CFR Part 60 compliant. A cogeneration facility chose Altech and their MIR 9000 to measure Nox, CO, CO2, N2O and O2. The system will be able to handle the difficult Nox conditions related to this facilities process. The O2 will be in-situ and there will be an opacity monitor. Altech is known throughout the industry for having expertise in the measurement of HCl. Often a difficult gas to accurately measure, the MIR 9000 is ideal for this application. A power plant in the Eastern U.S. chose Altech and the MIR 9000 to measure Nox, SO2, CO, CO2, HCl and O2. Altech will provide two MIR-9000's for a metals processing facility in the South that will monitor Nox, CO, SO2, CO2, O2, THC (VOCs) and Flow. This project will use Altech LCPD probe boxes. This is a good example of how the versatility of the MIR can allow for measurement of all of the mentioned gases with one analyzer.

Electronic treatment removes silica scale in power and semiconductor applications
Silicate has a special form, which is called covalent bond, but most scales have an ionic bond so ion exchangers or Reverse Osmosis Systems are available for removing them. But ion exchanger or RO System can’t remove silicate scale. In addition, silicate scale can’t be dissolved by acid cleaning. Also the magnet treatment developed in the West is subject to restriction in the size of pipe, flow velocity and so on. Furthermore, it is developed to remove scales caused by hard water. Its effect on soft water like in Japan has not been proved. Scalewatcher ,electronic water treatment equipment, made it possible to remove silicate scale which was impossible by chemical treatment or magnet treatment device within a short time

Xylem Flygt 4600 mixer used in lime slurry tanks and ore processing
The 4600 series mixers are ideal for lime slurries because of the two abrasion resistant options tungsten carbide or silicon carbide. With 8 different models, this makes it also a good option for ore processing. WCCR has superior sliding properties meaning considerably less wear between the two seal surfaces offering a longer life with less risk of leakage. It offers better mechanical strength and is far less brittle and sensitive to handling damage than SiC. WCCR has a binder where chromium, nickel and molybdenum have been added giving excellent corrosion resistance down to a pH of 3. SiC has the advantage when the pH is lower than 3 or when mixing small particles that are harder than WCCR.

Current and Future Trends in Water and Wastewater Treatment at Power Plants
This is an excellent report prepared by the UK's Department of Trade and Industry providing an assessment of the current state of development and application of water treatment technologies relating to utility and industrial scale fossil fuel-based power generation. Future areas of development are highlighted as well as the current state of the market and its future prospects. The power generation industry is predicted to remain a very significant industrial market for water treatment equipment and associated products. Increases in future global electricity demand are expected to be met primarily through large- scale fossil fuel-based power plants. Coal is projected to retain the largest share of power generation, but with natural gas-fired plants expected to become increasingly important. The main future markets for new fossil power plant are seen as China and India. China represents the largest single market in the world for new power plant equipment currently due to substantial long-term demand for increases in power supply. Coal is the main source of fuel for power generation in China and natural reserves are extensive. The use of coal is expected to grow substantially up to 2030, with the installation of new large-scale boiler plants. China is pursuing Clean Coal Technologies as a means of meeting future energy requirements, with supercritical boilers and Integrated Gasification Technology being attractive options. The power sector in India is dominated by coal and use is projected to increase threefold from 2000 to 2030. Ultraviolet technology along with ozone is sited as an emerging and novel treatment technology. There has been an increase in the use of UV technology as it eliminates the problems associated with the addition of chemicals with respect to factors such as disinfection by-product formation, safety factors in handling and storage, and economic factors. The use of UV radiation in conjunction with ozone or hydrogen peroxide can further enhance the efficacy of the overall disinfection process. Worldwide, with increasing limitations on clean water supplies and increasingly stringent environmental legislation, it is expected there will be a greater need to treat alternative low- quality water supplies. The successful application of these advanced technologies for treating such waters will be ever more important for future fossil fuel power generation.

Dr. Yougen Kong, P.E., Technical Development Manager at Solvay Chemicals, Inc., discussed dry injection of Trona or sodium bicarbonate, a low-cost solution to meet the SO2 and HCl limits in CSAPR, Utility MACT and Boiler MACT. Both Trona and Sodium bicarbonate are effective in reducing SO2 and HCl. Trona is slower to react and therefore less effective on SO2 but possibly better if all you want is HCl removal. Lots of the bicarbonate will be tied up in SO2 removal. So if you want to just remove HCl Trona may be the answer.

Keith Day, United Conveyor Corporation (UCC), described the results from several recent dry sorbent injection tests for simultaneous SO2 and HCl removal. Dry injection can achieve high removal efficiencies at low cost. There is a backlog of testing but the design and construction period is less than with scrubbers. So if you need to do something in a hurry this is a good route. In fact you can start with a portable unit and then move to a permanent unit later.

Desalination linked with 4000 MW coal fired Beijing power plant in Tianjin
A 4000 MW coal fired complex in Tianjin is using the waste heat from the plant to desalinate seawater. So far the cost is higher than the tarrif for surface water use in the area. But the potential is significant. Yellow color in the water was an initial problem but the cost is the main challenge. The yellow color is a problem with the distribution piping not the system.

Kasi Dubbs, Managing Consultant at Trinity Consultants, summarized the methods and processes used by EPA to set emission limits for the Utility MACT rule. Her presentation was particularly effective in showing the impact of EPA’s “Franken-plant” approach to setting the MACT floor. For example, of the top 20 performing units for PM, only one unit was also on the list of top 20 performing units for total suspended metals. Similarly, of the top 20 units for SO2, only one unit was also on the list of the top 20 units for HCl. She also identified other issues associated with EPA’s method for defining the “top performing 12%” of units in establishing the MACT floor.

Carl V. Weilert, Principal Process Engineer at Burns & McDonnell, discussed “The Good, the Bad and the Ugly” aspects of the proposed rule. On the positive side, he noted that the proposed rule allows for averaging among multiple units at a facility. On the negative side, he discussed why the test methods and processes for measuring total particulate matter were unreliable and questioned EPA’s assumption that dry sorbent injection (DSI) could be used to achieve compliance with the HCl limits. He also pointed out that the MACT limits for new units were too low and could effectively block any new fossil-fuel projects.

Greg Carleton of Pollution Control Services, Inc said that the majority of existing ESPs are not operating under their original design basis. Many existing ESPs have not been upgraded with modern operating philosophies or equipment. Taking a holistic approach in evaluating the precipitator in its current operating parameters permits a viable forward plan. It must take into consideration that the operating parameters have been modified as post combustion control equipment like SO3, NOx, and Hg control have been incorporated over the last few years.

Improving Precipitator Performance by Randy Cook - Alstom Power - Hot Topic Hour August 25, 2011
Randy Cook, Manager of Business Development at Alstom Power, Inc, observed that contrary to popular belief, many of the existing ESPs can be rebuilt to meet the stringent emission requirements of pending regulations. A combination of multiple technologies for mechanical and controls upgrade will have to be used in most installations depending on fuel, existing ESP sizing and configuration. Changing electrode geometry, installation of high frequency power supplies, optimized rapping, advanced controllers with opacity optimization, power down rapping, and off flow rapping can achieve significant PM emission reduction without adding plate area or replacing the ESP by a fabric filter. If upgrade of the ESP alone cannot meet the emission requirement, it may be cost-effective to install a downstream polishing fabric filter.

Market for WESP Stainless Plate
I talked to Buzz Reynolds of Siemens. He said all the specs call for 3/16” or greater plate. At Trimble County, they are using 6 moly and 2205 at Prairie State and Dallman. He thinks Spurlock is 2205 and Elm Rd. is 317 Lm. Buzz said they use a special design which was confidential but you could describe it as something more than 3/16. So maybe it is some shape other than just flat plate. : 1) How many WESPs have been installed? At least 100 world wide in power and thousands in acid mist and other chemical/refinery applications. Belco division of DuPont is big with the EDV in refineries. They may have close to 100 installations. The EDV is a hybrid between a WESP and a scrubber 2) Forecasted mkt for WESPs? It is about 5% of the potential of FGD but lots of stainless as a percentage of the total market. The problem may be the sizes do not fit your offerings 3) Approx Lbs of plate required per WESP…Power Plant WESPS are as big as the scrubbers. So there is lots of plate See the draft of the article in Air Pollution Control for more details on this market.

Increased Water Treatment Plant Capacity at Mexican Power Station
This paper describes the process and equipment used to treat a Mexican secondary water source in order to supply boiler feed make-up to a combined cycle power plant. RO pretreatment is provided by a highly efficient micro media filter that produces a filtrate with a turbidity of 0.1 – 0.2 NTU and an SDI value of 3 – 5. Following the RO, a compressed-bed ion exchange system was supplied to replace an existing electrodeionization polisher. The final product water produced has a conductivity less than 0.06 μS/cm.

At the March 17, 2011 Mcilvaine Hot Topic Hour, Dr. Desmond Smith, Ph.D. Vice-President at BRUKS Rockwood, Inc, discussed biomass handling and preparation prior to co-firing. Co-firing wood and biomass with coal in a suspension burning boiler requires that the fuel be prepared in specific ways to be effective in the way it performs. Conventional coal preparation machinery does not process biomass. It is necessary to control moisture to allow the machinery that grinds the organic fuel to produce a finely ground product that can be transported and injected pneumatically. The potential of using a gas to gas reheater such as Mitsubishi and Hitachi are using to reduce precipitator temperatures was discussed. A good way to extract heat from the system without paying an energy penalty would be quite attractive. ... Part 1 of 2

Brian Adair, Ph.D, Director of Technology Development at SCR-Tech, LLC a CoaLogix Company, discussed fuel impacts on SCR catalysts from a catalyst management perspective. SCR-Tech has experience with all types of catalyst (honeycomb, corrugated and plate-type) being exposed to all types of coals, blends, temperatures and operating conditions. Its unique perspective seeing all the catalyst types with the different fuels types has led to the following observations Consult your SCR Catalyst Manager to model fuel change impacts on catalyst life and system performance. Less expensive coal generally “trumps” more frequent catalyst replacement; but total economics and system performance must be evaluated. Most important factors to determine catalyst type, formulation and geometry: o Ash content o Sulfur content o Arsenic & calcium content o Operating temperatures o Flue gas velocity

Ruediger Peldszus, Senior Manager for Applied Technology Advanced Intermediates at Evonik Degussa GmbH, backed up his claim that TMT 15® is a good choice for separating heavy metals from flue gas scrubber water by citing a large number of installations in coal-fired power plants and also waste incineration plants. When asked how the chemical impacted the gypsum quality, Ruediger explained that the resultant compound is very small and exits the top of the hydroclone and not with the gypsum through the bottom. TMT 15 can also prevent mercury re-emission from the scrubber but for this to be successful, the parameters must be carefully evaluated.

Excellent cost to performance ratio for Duplex stainless in FGD demonstrated by Industeel
An analysis by Industeel based on a number of FGD installations demonstrates the corrosion resistance of duplex stainless. The cost advantage of duplex over austenitics has continued to increase. Industeel has prepared a selection guide based on chloride content in the recirculating slurry. Duplex has proved its advantages for most systems. However, where chloride levels are excessive Ni-base alloys should be considered. The super austenitic grade UNS S31266 can also be an alternative.

June 2009 marked the initial coal-fired operation of the world's first supercritical pulverized coal-fired low mass flux vertical tube Benson boiler. Jinzhushan 3, located in Hunan Province in the People's Republic of China, is a 600 MW B&W PGG VTUP™ once-through boiler with vertical tube furnace construction designed to burn Chinese anthracite using downshot pulverized coal technology. The boiler was supplied by Babcock & Wilcox Beijing Company, Ltd. (BWBC) under license from B&W PGG. This paper reviews the development history of supercritical, once-through steam generator technology and product advancements. Downshot pulverized coal combustion technology is used to efficiently utilize low volatile anthracite coal that is difficult to burn conventionally. The unique design features of the downshot combustion system are reviewed as well as the adaptation of this technology to the VTUP design. Both the SWUP and VTUP boiler designs can be supplied to meet the market requirements of today’s supercritical pulverized coal applications. The SWUP boiler represents a well-proven solution that provides consistent heat dis¬tribution to all tubes flowing through the furnace circuits making it insensitive to the natural variations that occur in furnace heat flux patterns that result from variations in fuel characteristics and types burned, boiler cleanliness conditions, air staging for combustion NOx control, and changes in pulverizer operating conditions. The VTUP boiler offers a solution that takes advantage of the benefits of natural circulation where tubes exposed to surges in heat flux will draw more flow to cool the tube instead of reducing flow due to higher resistance. The successful operation of Jinzhushan 3 demonstrates that this process works as expected and offers an alternative that has advantages of simpler construction, a less complicated wall support system, and lower furnace pressure drop contributing to more efficient net plant electric generation. Both the SWUP and VTUP furnace designs represent good alternative technologies for supercritical boiler applications that can be used to meet the needs of the modern power plant.

US Water ZLD System for Coal & Ethanol
McIlvaine interviewed U.S. water personnel at Electric Power about zero liquid discharge systems for power plants as well as biofuels. Information on the Patriot ethanol plant was provided. The following link provides a photo of the stand at Electric Power and a further link to details on the ZLD system at Patriot. This posting to the Global Knowledge Orchard is courtesy of Industeel, a supplier of steels used in ZLD systems. Patriot Renewable Fuels in Annawan IL. included the option to operate as a ZLD facility in the interests of conserving water.. During 2009, Patriot made the decision to voluntarily convert (as opposed to a regulatory mandate) to full ZLD operations and eliminate the discharge stream. Water usage was at approximately 2.9 gallons of water per gallon of ethanol produced prior to implementing ZLD. During the transition, water usage has been reduced to about 2.0 gallons per gallon of ethanol, nearly a one third reduction. This amounts to a savings of 100 million gallons of water per year. An article about this plant appears in Water World. http://www.waterworld.com/index/display/article-display/5870175047/articles/industrial-waterworld/volume-11/issue-2/feature-editorial/renewable-fuels-facility-implements-zero-liquid-discharge.html?cmpid=EnlWaterWorldIndustrialMay242011

As new regulations become more stringent and inclusive of additional requirements, utilities are being forced to modify the operation of their plants. Many are looking to their SCR catalyst to help meet these challenges. Choosing the optimum catalyst is an increasingly important decision because it not only ensures that utilities will comply with current regulations but it can also give utilities the flexibility to meet those that follow. Catalyst manufacturers continue to develop new catalysts that enhance the performance of the SCR, providing low cost solutions that give the required flexibility while minimizing the operational impact to the unit. This presentation will review the various factors that are part of the catalyst design and selection process including the catalyst performance requirements and the anticipated operating conditions. Discussion topics will include low load / low temperature operational impacts, SO2 to SO3 conversion minimization, mercury oxidation promotion on low halogen fuels, handling of large particle ash, and more. Finally, the operational and economic impacts of catalyst management programs will be reviewed.

This paper will take a brief look back at the history of SO3/H2SO4 concerns, from the “pseudo” particulate issues of the 1970s, current mitigation techniques, a review and comparison of extractive SO3 test methodology and the current need for real-time SO3 monitoring. The concern over SO3/H2SO4 formation in back-end coal fired boiler emissions has increased with the introduction of Selective Catalytic Reduction (SCR) units to control NOX emissions. Prior to SCR usage, it has been the corrosive nature of SO3/H2SO4 and its’ affect on downstream equipment and ductwork, that has fueled efforts to understand its’ formation and the means to control or mitigate its’ affects. In addition, SO3 emissions can cause opacity accidences, interfere with activated carbon control of mercury emissions and bias particulate test results. Wet chemistry test methods do not provide real-time data often needed to minimize additive fuel rates used to control SO3 emissions. To both lower opacity levels while maintaining ESP fly ash conditioning, a facility will undertake a series of process control modifications; additive feed rates, and even comparison of different additives. These operations are time consuming and costly. The use of a real-time SO3 monitor allows sources to make these changes and receive feedback in a timely and cost effective manner. A comparison of the Controlled Condensate wet method and real time monitor test results will also be provided. The benefits of a real-time SO3 analyzer (vs the CCM approach) will also be discussed as they pertain to ease of set-up and operation, results by method, cost, and the ability of each method to provide information in a timely manner.

Power facilities and others relying on water as a means of cooling may be facing the need to make significant changes to their intake system to be compliant with the pending 316(b) ruling. This ruling is promoting safer fish handling, among other environmental aspects, and the EPA is planning to identify the Best Technology Available (BTA), which may be a variety of solutions, cooling towers or closed loop systems at the top. Solutions Some groups propose that closed loop cooling systems are the best solution for 316(b) compliance and ultimately the most environmental friendly. While this may seem like a sustainable solution, for the plant it can require major construction to retrofit the facility to accommodate a closed loop system. This construction can be costly and require the plant to stop production for some time, or worse, close the plant down. Many of these facilities are facing very tight budgets and making the most economical decision is important. The decision must be made carefully, considering the risk of costing the community jobs, impacting the local economy and ecology. A large portion of the market affected by the most up to date 316(b) rulings are currently utilizing Once Through Cooling rather than Closed Loop Systems. If given the chance to implement alternative water screening and handling technology, power generators and others using cooling water must evaluate more effective and affordable solutions while still meeting the core requirements of 316(b). There are solutions that may satisfy the demands of environmentalist, the EPA, and power plants. During this discussion, a fair comparison on these alternative technologies will be presented, along with our best available EPA 316(b) ruling update.

Wet flue gas desulfurization (WFGD) Systems and the associated wastewater treatment (WWT) plants are typically designed separately with little or no direct communication of design conditions between vendors. In the current economic climate the emphasis on cost reductions thru improved design conditions and innovative design approaches is essential. The basic design factors for the purge stream are the volumetric rates of the purge stream, the chlorides concentration, and the weight percent solids. These factors have significant impacts to the costs of both the WFGD system and the downstream WWT system. The optimization of these design factors will minimize the overall design costs of project. This paper will examine the process and cost impacts of designs from five projects that have both a Siemens WFGD and a Siemens WWT system and provide design recommendations for future systems.

Ameren has been a leader in lowering NOx emissions. In 1990 AmerenUE, now Ameren Missouri, an Ameren subsidiary, implemented a long term emission reduction program. Based on NOx emission rates in 2009, Ameren had 13 of the top 20 plants nation-wide including the top 4 for T-fired coal units without SCRs. These reductions can be attributed to the addition of OFA, boiler tuning, utilization of combustion optimization software, and Ameren’s dedication to reducing NOx emissions by maintaining a group of combustion engineers. Ameren will discuss recent advances in this area.

The electrical generating community is aware of the U.S. EPA-proposed first-time nationwide regulations for handling and disposal of coal ash residuals (CCRs) including fly ash, bottom ash, and flue gas desulfurization (FGD) byproducts. Option one (Subtitle C) makes CCRs subject to hazardous waste requirements under the Resource Conservation and Recovery Act (RCRA). Option two (Subtitle D) establishes stringent requirements under non-hazardous classification similar to municipal solid waste rules, also under RCRA. The industry is buzzing with speculation regarding the form of the final rule, timing, litigation and how to influence change. The critical question is “what is this going to cost?” Timely budget planning, decisions, and actions are necessary to prepare for minimum requirements common to both options, with sufficient flexibility to adapt should the more stringent classification be approved. In addition to new dry disposal requirements, existing wet ash and FGD handling systems may be phased out entirely, requiring conversion of equipment, addition of dewatering systems, and closure of ash ponds. Some states already have similar disposal requirements; others have no such regulations. Using the combined resources of detailed cost analysis for specific sites, adjustments from municipal and hazardous waste regulations and costs, trade and association summaries, existing regulations, local economic conditions, computer models, and 30 years of disposal records for other wastes help to develop high confidence level cost estimates. This paper presents an up-to-the moment rule status summary, key points of the CCR proposal and discusses optional engineering solutions available for compliance along with associated costs using the Total Cost Accounting approach. Potential impacts on beneficial uses (recycling) of CCRs are difficult to predict but must be factored into the financial decision making process.

Dry Sorbent Injection (DSI) is being considered more frequently as a cost effective means of mitigating emissions of acid gases (SO2, SO3, HCl), heavy metals (Hg), and toxic organic compounds (dioxins and furans) from coal-fired boilers. A variety of dry sorbents are being considered, including sodium based compounds such as trona and sodium bicarbonate, calcium based compounds such as hydrated lime, and various activated carbons. Many existing power plants are equipped with electrostatic precipitators for controlling particulate emissions. Electrostatic precipitators can be very sensitive to operating conditions such as flow rate, temperature and to the quantity and chemistry of the particulate matter entering the ESP. Injection of sorbents upstream of an existing ESP changes both the quantity and the chemistry of the particulate entering the collector. This can change the performance of the ESP. When deciding whether to employ Dry Sorbent Injection, operators need to know what effect it will have on their existing equipment. Can they meet the required particulate emissions with existing equipment or will they need to upgrade their ESPs or even replace them with fabric filters? This paper will review several case studies wherein a variety of dry sorbents are injected upstream of an existing ESP. As will be discussed, the effects vary, depending on the design of the existing collector and on the amount and type of sorbent injected. The paper will also discuss mitigation options to enhance the performance of ESPs with dry sorbent injection.

An air pollution control system was installed at Dominion Generation’s Chesterfiled Plant in April 2008. The air pollution control system includes limestone injection, fabric filter, and a single absorber module to control emissions from the Chesterfiled plant’s number 6 boiler unit. The unit burns medium to high sulfur eastern bituminous coal. For sites such as this, a dry electrostatic precipitator has typically been used to control particulate emission. Recently, however, fabric filters have been installed at several installations to control particulate emissions under these conditions. With this type of emission control arrangement, ash loadings to the FGD are generally much lower than a typical dry ESP / Wet FGD arrangement. The are several advantages of operating a Wet FGD system with low ash loadings. Under this operating scenario, equilibrium inert / ash concentrations of the scrubber will remain quite low (usually under wt 2%) and absorber solids concentrations is mostly gypsum. Low concentrations of ash minimizes the potentialal of Wet FGD chemistry issues, such as aluminum fluoride blinding. Chemical analysis of the absorber slurries that are equipped with Fabric Filters upstream indicates lower concentrations of some dissolved metals, such as Selenium that is an important regulatory species. The low ash content of the FGD also results in very low gypsum moistures values (5% - 8%) to while operating with a typical hydroclone, vacuum filter system. Additionally, equipment wear is lessened as highly abrasive ash particles are not present in high quantities. SESS will present photos of absorber equipment from the most recent outage (September) 2010 at Chesterfield 6.

Over the past several years, a significant number of FGD systems have been placed in operation. At each site, absorber materials of construction have varied based on plant preferences and industry experience. A portion of absorber vessels were constructed of solids alloy material such as 6% moly stainless steel, alloy 255, alloy 2205, and 317 LMN. Other vessels were built out of carbon steel, lined with flakeglass or rubber. Also some FGD units were constructed of concrete that is lined with ceramic tile. This paper will examine several SESS installations that have utilized ceramic tile lined absorber vessels. The discussion will include design experience, general arrangement considerations, construction issues, and schedule limitations that must be considered with this absorber arrangement. In addition, internal inspection observation will be presented from several sites, including Dominion Chesterfield 6 , PPL Montour, PPL Brunner Island, and Constellation Brandon Shores.

Dry injection of sodium sorbents (trona and sodium bicarbonate) has been proven as an important multi-pollutant control technology due to (a) its low capital cost, (b) small installation, © easiness to operate, and (d) flexibility to fuel changes. Trona has been used as the main sodium sorbent due to its relatively low price. However, for some power plants where higher SO2 removal rates are desired and amount of generated fly ash need to be minimized, sodium bicarbonate (NaHCO3) offers a good alternative. For these reasons, a power plant that has been using trona since Fall 2005 tested conversion from trona to sodium bicarbonate on a 100 MW boiler. Trona or sodium bicarbonate was injected upstream of a hot-side ESP. The flue gas temperature at the injection point was around 600 oF. For 80% of SO2 removal, the normalized stoichemetric ratio (NSR) with trona was 2.5. With milled sodium bicarbonate, the required NSR for the same SO2 removal rate was decreased to 1.0. Over 97% of HCl was also removed. As a result, less sorbent was needed and significant savings in the sorbent was achieved. Furthermore, less fly ash was produced due to the sorbent change, and resulted in lower fly ash disposal cost. Same as trona, the sodium bicarbonate was able to keep the stack opacity below the limit since both sodium sorbents were able to lower the fly ash resistivity and thus enhance the ESP performance.

Draft U.S. Environmental Protection Agency hazardous air pollutant regulations for coal-fired utilities are anticipated by March 2011, and the expectation is that very high emission reductions (90% or greater) will be required for mercury control. Activated carbon injection (ACI) is expected to be a key tool for achieving these reductions; however, typical performance data with ACI suggest that in-flight mercury capture becomes exponentially more difficult at high reduction levels. Because of this decreasing sensitivity of mercury capture to carbon injection rate, ACI parameters will need to be optimized in order to consistently achieve high reduction targets. Unfortunately, optimization data may not exist for a number of plants since existing site-specific data may have been collected with outdated mercury capture targets in mind, and the ultimate capture potential or its sensitivity to plant operations was not thoroughly examined. To add to this dilemma, optimizing the maximum mercury reduction with ACI is not a trivial matter since there are number of potential bottlenecks that can limit overall capture. These restrictions range from insufficient sorbent distribution and contact time in the flue gas, to one of many kinetic limitations that arise under the conditions encountered in flue gas. This presentation will discuss the common mechanisms that limit mercury capture with ACI, as identified through fundamental study of mercury–carbon interactions and analysis of pilot and field data. Recognizing the typical trends with mercury capture can assist in the selection of ACI parameters that are most likely to achieve high reductions that may be mandated in the near future.

Based on a Federal Court decision the US EPA has agreed to propose the National Emission Standards for Hazardous Air Pollutants (NESHAP) for Coal- and Oil-Fired Electric Utility Steam Generating Units. This NESHAP is to be proposed by March 16, 2011 and promulgated by November 16th, 2011. This NESHAP, and the associated requirements for MACT (Maximum Achievable Control Technology), are expected to be very similar in form to the Industrial Boiler MACT. The MACT floor, based on EPA regulations, cannot be less stringent than the average emission limitation achieved by the best performing 12% of existing sources for subcategories with 30 or more sources, or the best-performing 5 sources for subcategories with fewer than 30 sources. Accordingly at least 90% of the Utility industry will be affected by the emission standards promulgated under this MACT. The MACT requirements will require upgrades and modifications to existing emissions control equipment and the installation of new control systems to limit emissions of mercury, the other criteria metals, acid gases such as HCl, and organics. This presentation will address the potential impacts on existing Utility Assets and discuss the implications and limitations of existing control technology to control the air pollutants addressed by this NESHAP.

Study was conducted at a 5-MW equivalent slipstream facility of Gulf Power’s Plant Crist Unit 5 located in Pensacola, FL. The facility is also commonly referred to as Mercury Research Center (MRC). During the trials lasting 10 days, the effect of a range of process variables was studied. The variables included flue gas temperature, air-to-cloth ratios, interval between cleaning, and the effect of removing some of the fly ash by an ESP upstream of baghouse, etc. GE tested a novel membrane-based filtration media formed as pleated elements. Data will be presented that shows that by using GE’s novel filtration elements, Mercury capture as high as 98% can be achieved by inherent fly ash alone (without needing to inject powdered activated carbon). This was true in spite of majority (about 80%) of Mercury being in elemental form in the flue gas. Traditional round filter bags are typically known to capture around 30 to 40% of Mercury in the flue gas by inherent fly ash. Data was also collected with injection of activated carbon upstream of baghouse. It was found that by using these novel filtration elements, if a plant is already using powdered activated carbon the consumption of activated carbon can be reduced by as much as 85%. Data will be reviewed along with the proposal of mechanisms about how this novel filtration element works in achieving such high Mercury captures, as compared to traditional round bags.

Richard (Rich) Staehle, Vice-president of Business Development at Marsulex Environmental Technologies, related the evidence to show how high efficiency FGD using ammonia instead of limestone (AS-FGD) has been commercially demonstrated in full-scale systems for well over a decade. This process uses the SO2 as a feedstock in the production of ammonium sulfate, a valuable crop fertilizer. In addition to significant revenue potential from the fertilizer sales, this technology minimizes or eliminates the solid and liquid waste costs and liabilities associated with conventional FGD systems. Experience at Dakota Gasification is that this granular fertilizer is preferred over alternatives. Therefore a big storage dome supplied because of assumed seasonal demand has not been needed. As soon as it is produced the ammonium sulfate is sold.

Eric Erickson of Haldor Topsoe updated participants on the Haldor Topsoe SNOX technology, an exothermic, catalytic process for the removal of SO2 and NOx from flue gas. SNOX generates additional heat recovery and merchant grade sulfuric acid. It is ideal for high sulfur coal and petcoke applications as it becomes more efficient and cost effective as the sulfur content of the fuel increases. In the discussion period it was agreed that this process can easily be adapted to the new toxic regulations by using sodium additives ahead of the particulate device to remove the HCl (without injecting enough to remove SO2).

Lisa JN Bradley, Ph.D., DABT, Senior Toxicologist and Vice President Environment at AECOM, discussed “Perspectives on Health Risks Associated with Beneficial Re‐Use of Byproducts of Coal Combustion.” EPA stated in their June 2010 proposed rule for the disposal of coal combustion residuals (CCRs) that their intention was to preserve the Bevill exemption for the beneficial use of CCRs. However, the preamble to the proposal was essentially an advanced notice of proposed rulemaking for the regulation of these uses. This contradiction was evident in testimony given by EPA at the recent hearing of the House subcommittee on Environment and the Economy on the McKinley bill (HR 1391). EPA’s Office of the Inspector General has also recently issued a report titled “EPA Promoted the Use of Coal Ash Products with Incomplete Risk Information.” Her talk provided encouraging results for risk assessments and risk-based evaluations for the beneficial uses of CCRs, and how EPA’s own CCR risk assessment can help inform the issue.

Power Industry Experience Using Micro Media Filtration and Short Bed Ion Exchange Geoff Hong, Eco-Tec Inc. With the demand for higher efficiencies and lower maintenance and operating costs for boilers and turbines, high purity water treatment systems are becoming more crucial to the operation of power plants. Modern power plants, operating at supercritical and ultra supercritical boiler pressures and temperatures, require such high purity water that it is approaching theoretical levels. High efficiency gas-fired combustion turbines, which use high purity water for NOx control and sprint mode, heat recovery steam generators and once through steam generators also require high purity water for the same reasons. Effective pre-treatment for reverse osmosis (RO) and ion exchange (IX) demineralizer systems not only contributes to the production of high purity water, but also helps to reduce the operating and maintenance costs of those systems. The versatility and efficiency of short bed ion exchange systems produce high purity water from feeds of variable characteristics, with lower chemicals consumption and waste volumes. This paper discusses the use of micro media filtration as a pre-treatment for RO or IX systems and the use of short bed IX systems for the production of high purity boiler feed make up water and condensate polishing. The experiences of several installations are outlined for applications in power generation and cogeneration plants.

RO Membrane Pretreatment Ken Robinson, Avista Technologies Pretreatment continues to be a subject that turns up on a daily basis when dealing with RO (Reverse Osmosis) process. Even though pretreatment requirements are well established for RO, the power utility market as a whole tends to see more of these issues as compared to other industries. Part of the reason for this trend is that feed water supplies tend to originate from surface sources while other factors tend to be more directed at equipment and design specifications. This presentation will focus on a number of pretreatment strategies that various power utilities have dealt with over the course of the last couple of years. RO system cases involving softening, coagulation, ultrafiltration, and media filtration will be covered along with RO process issues such as scaling, filtration, and biogrowth. In each of these cases, solutions will be presented on how to best mitigate the problems and show how analytical techniques can be used to fine tune and minimize the impact of the problems.

A New Approach to On-line Sodium Measurement David Gray, Mettler-Toledo Thornton, Inc. Sodium has been a critical measurement parameter for ensuring water treatment performance and purity for nearly four decades. Monitoring cation exchange performance and the purity of makeup water, steam and condensate has benefitted from measurement of this key parameter. Many refinements have been made to the ion-selective electrode method for on-line sodium measurement for these applications. Described here are yet further improvements to this technology including an unique integrated electrode system that measures both sodium and pH to assure proper reagent delivery. The system design minimizes reagent consumption and reduces maintenance requirements well below current practice. The new sodium system uses a particularly simple automatic calibration method and also provides the ability to measure grab samples easily. Its implementation with an operator interface common to other parameters including conductivity, dissolved oxygen, pH and ORP makes it especially convenient for installation and operator training.

Comparison of Dissolved Oxygen Measurement Technologies Kenneth Kuruc, Hach Company Dissolved oxygen measurement in the steam cycle remains a key parameter for the monitoring and control of corrosion. A variety of methods, including colorimetric and electrochemical (galvanic and polarographic), continue to be employed as either field test, portable or process platforms. However, most methods to this point have required a fair amount of attention and expense in order to maintain proper operation. In this paper we will discuss the traditional methods along with a relatively new technology known as “optical” or “luminescence”. The significance and potential advantages of this new technology for the power industry will then be considered.

Do Neutralizing Amines Have a Role in the Treatment of High Purity Boiler Feedwater? James (Jim) Robinson, Luis Carvalho, Robin Kluck, Richard Krichten, GE Power & Water – Water & Process Technologies Neutralizing amines have been widely used to treat high purity boiler feedwater since at least the 1940s. Notable benefits have been derived, however some consider the use of these amines to be risky. In addition the use of organic chemicals for boiler feedwater treatment often causes steam and condensate cation conductivity levels to exceed current power industry and steam turbine vendor guidelines. The benefits that can be derived and questions concerning the use of neutralizing amines are presented to help plant operators assess the potential value of using them in their systems.

Overview of Microbiological Control & Monitoring In Utility Cooling Systems K. Anthony Selby, Water Technology Consultants, Inc. Cooling water systems in electric utility plants face challenges related to corrosion, mineral scale deposition, microbiological fouling, and suspended solids accumulation. Of these challenges, microbiological control is a primary issue because it can impact the others. In addition to a direct impact on heat transfer, microbiological growth can influence corrosion, trigger mineral scale formation, and accelerate suspended solids accumulation. This overview will discuss the common methods of microbiological control in power plants as well as discussing some emerging technologies. It will also emphasize the importance of monitoring the effectiveness of microbiological control and discuss current monitoring methodology.

On-Line Water Chemistry Measurements for Power Plants Ravi Jethra, Fred Kohlmann, Bhupen Patel, Endress + Hauser Inc. At the center of every efficient power plant, there is a well run water treatment system. Correct water treatment is crucial to provide high purity water to pre heater, boiler, steam and condensate systems, as well as other systems using boiling-water reactors and pressurized water reactors. The quality of makeup and feed-water is required to be monitored continuously to detect chaining water quality parameters (WQP). These changes in WQP usually indicate maintenance, upsets, leaks, and carryover. The long term data review of WQP also helps to study the gradual trends for prevention of corrosion or scaling. In case of inadequate measuring systems, these conditions may result in increased or unscheduled maintenance, higher capital cost, lower efficiency of heat transfer surfaces, and less profits due to down time. As newer and better technologies increase the power plant efficiencies in other area, the allowable limits on water quality become increasing important. Therefore, the requirements of WQP measurements become more important. The paper discusses data from case histories on water quality. In addition, the authors discuss how WQP measurements can be utilized to implement savings in reagents in the treatment process. The information presented in this paper would be helpful to operations managers, maintenance staff, and process owners of water treatments associated with power and steam utilities.

Karin Madsen of Haldor Topsoe discussed the effect of operating conditions and catalyst type on mercury oxidation across the SCR catalyst. Up to 90 percent mercury oxidation is achievable depending on the inlet Hg speciation and the chlorine concentration. Greater than 91 percent mercury removal is achievable using existing control devices (the combination of the SCR-FGD strategy). Adding additional HCl above a certain point does not improve oxidation. However, bromine acts differently and therefore may provide greater oxidation with increased amounts.

Shiaw Tseng, Marketing Manager at Graymont, Inc., described a multi-pollutant control system for existing coal-fired power plants using lime-based Circulating Dry Scrubbers (CDS) to remove SO2, SO3, HCl, and HF. He presented the results of performance guarantee tests conducted at the AES Greenidge Station Unit #4 (107 MW) burning eastern bituminous coal (2.5 to 3 percent sulfur) with a CDS and baghouse. These tests showed pretty impressive reductions of SO2, SO3, Hg and HCl to levels that were well under the limits in the proposed utility MACT. Advantages of this system include a relatively small footprint, fuel flexibility (including biomass), low water consumption and dry byproducts (no wet sludge). Interestingly, the CDS system achieved better mercury reduction than using ACI under the same operating conditions, indicating that ACI is not required. These systems are currently operating at 14 plants in the U.S.

Dr. Sebastian Hirschberg, Manager of R&D Energy and Environment, Mixing and Reaction Technology at Sulzer Chemtech Ltd, called in from Switzerland describing how power plant operators can improve SCR reactor performance and save money by installing and using Sulzer static mixers. The primary point of his presentation was that properly designed static mixers with CFD modeling can eliminate the need for injection lances with their problems, while increasing catalyst life, improving NOx reduction and reducing pressure drop. An arc wire coating is also available to increase the service life in highly abrasive environments. There are over 35 plants in the U.S. using these Sulzer mixers.

Robert (Bob) Crynack, Business Development Manager for the Peroxygen Division of FMC Corporation, described a process under development by FMC that utilizes hydrogen peroxide to control NOx from combustion sources and industrial processes. Injection of peroxide into existing ducts oxidizes the NOx, primarily NO, to other nitrogen species that can be captured by existing downstream equipment such as wet scrubbers, CFB scrubbers, spray dryer absorbers or dry injection (lime/trona) with ESP or FF. The technology is intended for coal-fired power plants that desire NOx reductions of 40-80 percent with minimal capital investment and low operating and maintenance cost. While it has been proven that hydrogen peroxide will oxidize NO, NO2 and even mercury, the ability of downstream equipment to capture the NOx and mercury are still being evaluated.

New DeNOx Approaches by Dr. Brian Adair, CoaLogix - Hot Topic Hour April 7, 2011
Brian Adair, Director of Technology at CoaLogix, coined a new term in his presentation calling SRCs “Multi-Pollutant Reduction Reactors” or MPRRs because they should now be looked at as devices to control SO3 and mercury as well as NOx. The focus of his talk was why an operator should treat a catalyst as an asset rather than a consumable. He stated that operators need to balance the different goals of deNOx, SO2 conversion, NH3 usage, pressure drop and mercury oxidation and to have a different way of long term planning. When a catalyst layer is no longer optimum for the operating conditions, it can be traded in for a different type or formulation or sold to another plant where it will achieve their objectives.

Jim Sutton, Director at Alstom Power, discussed CO2 reduction through increasing energy efficiency in coal-fired boilers. Lots of CO2 could be avoided by making improvements in many areas. For example just using a more efficient transformer rectifier with a precipitator significantly reduced the parasitic load. There is a huge potential when the average heat rate for the U.S. fleet is 10,761 Btu/kW-hr for an efficiency of only 31 percent. Jim showed a group of older power plants with heat rates above 15,000 Btu/kW-hr, so the potential CO2 reduction for these old power plants is very large.

Jeffrey Phillips, a Senior Program Manager at the Electric Power Research Institute (EPRI), provided an overview of the U.S. Dept. of Energy's and Ohio Coal Development Office's Advanced Ultrasupercritical Boiler and Steam Turbine Materials Development Program. This is a $50 million, 9-year effort aimed at increasing steam temperatures by more than 250°F above the current state-of-the-art. This remarkable effort has now resulted in a code case submission to the ASME Boiler Code committee for a new material which can operate at the targeted conditions. Approval of this material will open the door to the most significant improvement in the thermodynamic performance of coal-fired power plants in 50 years. You can learn more about this at an April 7 conference also covered in this Alert. One of the important discussions following the talk was regarding the possibility to design new coal-fired boilers to eventually operate in the advanced ultrasupercritical state but to initially operate at efficiencies substantially higher than the old power plants they replace. So the old plants could be immediately replaced with major benefits. Then in 2020 when the advanced ultrasupercritical materials are commercial, the plants can be retrofitted for this additional efficiency boost.

Keith L. Pronske, President and Chief Executive Officer of Clean Energy Systems (CES), covered technology derived from the aerospace industry. Pressurized oxy-combustion of coal can create a zero emissions power plant. Future coal-based power generation systems may utilize de-carbonizing technologies that permit carbon dioxide (CO2) to be captured and stored. Oxy-combustion of gasified coal (synthesis gas or “syngas”) permits capture and utilization of high quality CO2. In the oxy-combustion power plant cycle proposed by CES, syngas and high-quality oxygen provided by an air separation unit (ASU) are combusted to form a working fluid composed primarily of steam and CO2. This high-temperature gas directly drives turbines to produce electricity, after which the steam is condensed and the CO2 is captured and stored. This technology enables use of coal or other hydrocarbon fuels with essentially zero atmospheric emissions. Biofuels can be gasified along with the coal. Thus this system would be even greener than solar or wind. It could be a net CO2 reducer. Every kWh of electricity generated results in extraction of CO2 from the atmosphere.

Co-firing Wood with Coal by Desmond Smith, BRUKS Rockwood. Hot Topic Hour March 17, 2011
Dr. Desmond Smith, Ph.D. Vice-President at BRUKS Rockwood, Inc, discussed biomass handling and preparation prior to co-firing. Co-firing wood and biomass with coal in a suspension burning boiler requires that the fuel be prepared in specific ways to be effective in the way it performs. Conventional coal preparation machinery does not process biomass. It is necessary to control moisture to allow the machinery that grinds the organic fuel to produce a finely ground product that can be transported and injected pneumatically. The potential of using a gas to gas reheater such as Mitsubishi and Hitachi are using to reduce precipitator temperatures was discussed. A good way to extract heat from the system without paying an energy penalty would be quite attractive.

Dr. Fernando Preto, Senior Scientist and Group Leader for Biomass Conversion at CANMET Energy Technology Centre, discussed the co-firing of lignite with wood (pine) residues and peat focusing on emissions and ash deposition. His presentation reviewed the effects of fuel blending ratios, excess air, and moisture content on air emissions (CO, SO2 and NOx) from co-combustion of wood residues and peat with lignite. Co-firing leads to significant differences in the concentrations of some major inorganic compounds (e.g. SiO2, CaO, MgO, SO3) in deposited ashes. There was a discussion of the combustion of municipal waste (MSW). Fernando made a very important point. Their research shows that the presence of sulfur reduces dioxin formation. So burning MSW in a coal-fired boiler has a beneficial impact on emissions. McIlvaine pointed out the advantages of using the chlorine in the waste to convert mercury to a soluble form. It was further observed that with the new Utility MACT rules power plants will have the air pollution controls to deal with MSW.

Ajay Kasarabada, an Air Permitting Manager in Black & Veatch Energy Division's Environmental Management Services Section, and Diane Fischer, Manager of Business Development for Air Quality Control Projects for Black & Veatch’s Power Generation Services, described a method for avoiding the need to comply with the Boiler MACT – “the non-solid fuel pathway”. They presented a methodology by which boiler operators can evaluate the technical and economic issues related to converting boilers to operate on “Gas 1” or “Other Gas 1” as defined by the EPA or decommissioning solid fueled boilers and installing new gas-fired boilers or gas turbines. Gas 1 units, Other Gas 1 units and combustion turbines do not have to meet Boiler MACT emission limits. Diane’s portion of the presentation focused on the benefits of considering co-generation and provided a detailed methodology for evaluating this alternative. They indicated that Black and Veatch is involved in studying these alternatives for a number of boiler operators but they have not yet reached any firm conclusions.

Enhanced Mercury Oxidization (EMO) by Steve Baloga, Shaw - Hot Topic Hour March 10, 2011
Steve Baloga P.E., a Senior Environmental Consultant at Shaw Environmental & Infrastructure, described a process for economically reducing mercury emissions from boilers combusting bituminous or sub-bituminous coal. EMO™, a liquid brominated oxidant, is injected into the gas stream at the exit of the boiler or economizer to convert elemental mercury into the oxidized version that is more readily captured by existing control equipment. With very low injection rates, this can be an effective low cost solution to achieve the new lower limits required by the MACT. He presented data on several boiler trials that demonstrate the viability of this low cost approach.

A key point made was that although EPA indicated that because of concerns over the legality of the significant changes between proposed rule and final rule, EPA is taking comment on the final rule, any delay in or stay of the deadline for compliance is very unlikely. He also emphasized that affected boiler operators must do whatever is necessary to comply with the new emission limits. Just installing additional control equipment will not be sufficient.

Industrial Boiler MACT - Impact and Control Options - Webinar March 10, 2011
On February 23, 2011 the U.S. EPA issued “Sensible Standards” for Boilers and Certain Incinerators that cut the cost of implementation by about 50 percent from an earlier proposal issued last year. Because the final standards significantly differ from the proposals, EPA believes further public review is required. Therefore, EPA will reconsider the final standards under a Clean Air Act process that allows the agency to seek additional public review and comment to ensure full transparency. EPA's reconsideration will cover the emissions standards for large and small boilers and for solid waste incinerators.

David Early of Combustion Technologies Corp. told attendees that combustion optimization at coal-fired power plants can be achieved with the use of various instruments that are available today but did not exist just a few years ago. Low NOx burners give power plants the ability to control air to each burner - yet most don't have a measurement to tell how MUCH air each burner is getting. Accurate measurement of burner secondary air (SA) is now available for ANY low NOx burner so that control with the burner SA can be optimized. Likewise, the amount of coal flow to each burner can be continuously measured and controlled for best combustion practices. Combined, these devices can be used for continuous control and provide for significant efficiency increases. Also the CO can be measured and controlled.

Brad Hilton, USA Coordinator and Technical Director for Bachmann Dampjoint, Inc. (BDI), discussed both metal and fabric joints with the focus on two applications in the high temperature zone. These included penetrations to the boiler itself and in the economizer region. One of the interesting options is to use the existing leaking metal joint and to encompass it with a fabric joint. The metal joint then becomes the liner for the fabric joint.

Expansion Joint Proper Design by Christopher Dyjak, Effox-Flextor - Hot Topic Hour February 24, 2011
Christopher L. Dyjak, Manager for Expansion Joints at Effox-Flextor, a CECO Environmental Company, emphasized the importance of utilizing proper application information in the initial design of expansion joints. One example is a joint in an FGD system. If the temperature could potentially drop to the dew point, then it is a more difficult application than if there were not the risk of acid corrosion. External insulation is recommended when the temperatures will never exceed the fabric limit and there is the potential for acid condensation.

John Darrow, Associate at W. L. Gore & Associates, Inc., discussed expanded polytetra-fluoroethylene (ePTFE) based products that could provide solutions to new compliance challenges for PM, dioxin/furan (D/F) and mercury. There was a summary of the potential for ePTFE membrane filter bags for PM control, REMDIA catalytic filtration systems for D/F control and a new carbon polymer composite material for mercury control. The composite material was of great interest to the participants who asked about pressure drop (low), efficiency (70-90 percent in addition to the scrubber removal) and elemental mercury removal (high). Testing is taking place at the Southern Yates station with EPRI also involved. This technology could be used as a second step if the initial attempt to remove mercury in the scrubber falls short. Since this device follows the scrubber it is better suited for a plant with a scrubber. Activated carbon would be injected ahead of the scrubber and would have the effect of reducing the amount removed in the scrubber. Therefore large amounts of carbon would be required to gain small efficiency increases.

Boiler MACT? - Prelude to Utility MACT by Robert Fraser, AECOM - Hot Topic Hour February 17, 2011
Robert (Bob) Fraser, QEP, Senior Technical Director for Power Generation Services at AECOM Environment, reported that the Utility MACT rule is likely to follow the form of the Industrial MACT rule which is now most likely to be issued on February 21st. EPA is using the same general procedures to develop both sets of standards. One of the concerns is the organics limits for both the Industrial and Utility MACT may be inversely rather than directly proportional to the CO. During startup and shut down there are high levels of CO and this could be a problem. It may be better to address dioxins and furans under work practice standards rather than limits.

Improving ESP Performance Webinar - Hot Topic Hour January 20, 2010
ESP Performance Improvement can be Substantial - Hot Topic Conclusion on January 20 There has been lots of focus on replacing ESPs with baghouses to meet upcoming regulations. The speakers in the Hot Topic Hour yesterday said there is an alternative. You can upgrade existing ESPs and achieve results which may satisfy future requirements. Dr. Yougen Kong, P.E., Technical Development Manager at Solvay Chemicals, Inc., told the attendees that “there is a better alternative to SO3 for conditioning electrostatic precipitators.” Trona addition system is simple and its capital cost is much lower than that of a SO3 production and injection system. Trona is relatively inexpensive and can be injected in several places. Mick Chambers, Southern Environmental, Inc, said that you can upgrade your ESP and with halogen-based additives in the coal, you can meet the particulate and mercury regulations. He showed that the SCA of recent installations has been relatively low and yet the performance high. So the footprint of a retrofit does not have to be large. When asked about the wet ESP using a fabric for the collection plate, Mick said that it is a good option and successful on industrial boilers and process applications. We were sorry to learn that John Caine passed away in a tractor accident last September. John had represented SEI in several of our previous Hot Topic Hours and has long been a contributor to the industry. Steve Jaasund, Manager Geoenergy Division A. H. Lundberg Associates, made a case for adding a wet ESP after the FGD system to meet the upcoming MACT regulations. In the discussion period it was speculated that the new mass monitoring requirements would make it more difficult for dry ESPs to meet emission limits. The wet ESP will eliminate the exceedance spikes associated with a stand-alone dry ESP. Paul Leanza of Pollution Control Services, Inc. indicated that many utilities have the opportunity to greatly improve performance of their existing precipitators. He indicated that 50 percent of the emissions occur during rapping (rapping reentrainment). These particles are relatively large and do not cause opacity spikes proportional to the mass increase. It was speculated that with mass monitoring this phenomenon will be an unpleasant surprise. Emissions will be higher with mass monitors than they were thought to be with opacity monitors and periodic stack testing. Ron Landreth of Albemarle was pleased to find that their brominated PAC actually improves precipitator performance whereas the non-brominated PAC may add to emissions. So it is worth considering brominated PAC to capture mercury and reduce particulate. Jean Bustard of ADA-ES (ADA Environmental Solutions LLC) related experience with a proprietary conditioning chemical which has performed well and does not impact mercury capture with PAC. The company offers another approach to conditioning hot side precipitators.

Gary D. Mooney, Sales Engineer Clyde Bergemann Delta Ducon (CBDD), discussed four viable bottom ash systems and solutions that can be retrofitted to existing power plants desiring or being required to remove an ash pond. Two systems involve replacement of the existing equipment under the boiler while two more retain the existing boiler island equipment and divert the ash slurry to new dewatering equipment. Many power plants are using wet sluices for bottom ash. The dry system has the advantage of increasing boiler efficiency if only slightly. The other systems are easier retrofits in many instances.

Patrick Garcia Strickland, Laboratory Director at Frontier GeoSciences, Inc., discussed metals mobility in coal combustion residues and analytical techniques for monitoring flyash ponds. Knowledge of the ability of metals to be released from coal combustion residues is an important factor in determining the potential effects on the environment. At the end of the presentation there was a discussion of the benefits of leaching the metals out of the flyash at the plant site. Coal –fired power plants can make 30 percent hydrochloric acid and at the same time leach metals from the flyash. The metals are captured in ion exchange resins and the purified acid is sold. This will make higher chlorine coals more attractive and result in a metal free fly ash, rare metals, hydrochloric acid and gypsum as byproducts.

Coal Ash Ponds and Ash Disposal Issues Webinar - Part II - Hot Topic Hour January 14, 2011
Two very enlightening days of discussions on the CCR issue. The extended period for public comments on the proposed rule on Coal Combustion Residuals (CCR) (commonly referred to as coal ash) concluded on November 18, 2010. According to the speakers we can expect a final rule promulgated in 2011 or 2012. The big question is “Will the final rule classify CCR as special wastes subject to regulation under Subtitle C of RCRA (Resource Conservation and Recovery Act) when destined for disposal in landfills or surface impoundments (essentially hazardous waste) or as non-hazardous wastes regulated under Subtitle D of RCRA?” If EPA decides to classify CCR as “hazardous,” under Subtitle C, EPA would create federally enforceable requirements for ash management, including waste generation, transportation and disposal. If CCR is declared non hazardous, under Subtitle D, EPA would only mandate a set of minimum national standards and leave it up to state governments and citizen litigation to enforce them.

Joshua R. More, Partner Schiff Hardin LLP, described how in working with state regulators a utility was able to close an unlined surface impoundment. Like most states, surface impoundments in Illinois are regulated under groundwater quality rules. These rules provide for protection of groundwater quality and do not specifically address design or closure standards for surface impoundments. The Illinois Environmental Protection Agency initially proposed to regulate the closure of surface impoundments under the landfill rules. However, the landfill rules were promulgated after many of the CCR impoundments in Illinois were built, specifically exclude surface impoundments and include numerous design criteria that are impractical for surface impoundments. Therefore, the utility and its legal team, supported by technical analyses from its environmental consulting team, worked with the state to develop a set of site-specific rules governing closure of a CCR impoundment. The site specific rule has become the model for closing CCR impoundments in the State of Illinois.

EPA Has the Ball by Tom Adams, American Coal Ash Association - Hot Topic Hour January 13, 2011
Tom Adams, Executive Director American Coal Ash Association (ACAA), explains that there is a wide range of opinion on what the impact of a hazardous waste regulation would be on the future of beneficial use of CCP. The agency believes it can exempt preferred beneficial uses from any hazardous waste regulations, and markets for those preferred beneficial uses will be unaffected, at the least, or flourish as generators will invest in technologies to make their CCP more attractive to the end users. In over eighteen months of discussions with CCP marketers, project owners, engineers and architects, contractors, material producers and other stakeholders, the ACAA has determined that the U.S. EPA is wrong in its prediction of market behavior. The stigma of association with hazardous waste regulations and potential liability exposure are primary concerns in the marketplace.

Richard (Rich) Miller, Vice-President of Business Development for Utility Systems at ADA Environmental Solutions (ADA-ES), showed timelines which dictate that boiler operators start mercury testing soon. There are lots of unknowns due to the wide variety of fuels and boiler configurations. With the potential of large carbon needs by the utility and cement industries, supply could be an issue. Mercury reduction guarantees are going to be tough to provide since the need is a mass emission level and not a percent removal. Furthermore the 0.2 lbs/TBtu limit for biomass boilers will be difficult to measure as well as guarantee.

Industrial Boiler MACT: CEM Requirements by Dan Kietzer, Sick - Hot Topic Hour November 19, 2010
Dan Kietzer, Environmental Market Manager at Sick Maihak, Inc., covered CEMS for particulate and CO and CEMS requirements. The company has sold more than 50 PM CEMS using the scattered light principle to power plants in the U.S. Some were to meet consent decrees which mandated installation of PM CEMS. The scattered light approach can provide accurate mass measurement in either dry or wet stacks. In wet stacks the sample gas is withdrawn and heated prior to measurement. An insitu CEMs for CO can also measure CO2 and H2O.

J. Patrick Stevens, Associate and Senior Consultant at Golder Associates Inc., told participants about a survey of 16 biomass-fired boilers in the wood products industry to determine whether or not they would meet the proposed existing source Boiler MACT limits for biomass-fired boilers. CO was one pollutant that would create a challenge. Four boilers would require no improvement. Twelve boilers will require from 13 to 79 percent reduction in CO. Nine of these would require end of pipe controls while three could improve fuel handling and combustion.

David W. South, Manager of Business Development at Amerex, drew from a considerable bank of experience the company has gained with some 50 MACT related boiler installations in the last five years. One unit on a PC boiler with carbon injection and a fabric filter is using 2.2 lbs/MMacf of B-PAC. Inlet mercury is 20 lbs/TBtu versus 2.5 lbs/TBtu on the outlet. Another with only 2.0 lbs/MMacf is reducing mercury from 25 lbs/TBtu to less than 2 lbs/TBtu.

Robert (Bob) Fraser, Senior Technical Director at AECOM Environment, discussed AECOM’s experience to date with the boiler MACT. He indicated that no one plant is now demonstrating the ability to meet all the pollutant requirements. There is very little data on CO and dioxins. It may be necessary to install back end CO and dioxin controls. These could be quite expensive. Minimizing the time at which the gas is in the 800-460 degrees F range by quenching should be effective in avoiding dioxin formation, but this is not an option where downstream fabric filters are being operated. One big question is whether a source which switches fuels to meet the MACT would then be a “new MACT source.” If a new permit is required because of fuel switching, then it is very possible that the source would be considered “new.”

Jon Miller, Technical Support Engineer at Albemarle Corporation, explained that M-PACT is an equipment package to inject activated carbon at much lower cost than a custom design. The first M-PACT unit was sold in 2007 and is providing reliable 90 percent mercury reduction. There are a number of components in the larger systems which are critical. One is the choice of blower for the pneumatic conveying. A regenerative blower is less expensive but has a lower pressure output and is less tolerant of dirty environments. A Roots type PD blower is more expensive but capable of higher pressures and will tolerate some dust.

Carroll "Mack" W. McGuffey III, Associate at Troutman Sanders LLP, told the participants that it is unlikely that the final rule will be delayed by lawsuits. The litigants can petition to stay the rule until the litigation is complete but the D.C. Circuit Court is unlikely to do so. So the clock will be ticking and compliance will be required in 2014. The lawsuits can focus on several issues. One is the lack of five or more sources achieving the limits on any one pollutant. Another is the argument that a source which achieves the limit on one pollutant but not another is not a valid example.

Dave Novogoratz, Business Development Manager for the Particulate Control Group at Babcock & Wilcox Power Generation Group, Inc., indicated that the requirement for PM CEMS for boilers over 250 MMBtu/hr and for CO CEMS add some new challenges. The CO limit requirements may require thermal oxidizers or CO catalyst for grate-fired units. Wet ESPs may have a place downstream of wet particulate scrubbers to meet the new PM requirements. ACI, SDA, scrubbers, fabric filters, and oxidation catalyst might be options for dioxin and furan control. Compliance will require a system solution that also takes into account other upcoming regulatory requirements.

Dibasic Acid from Invista for Higher SO2 Removal Efficiency
Invista DBA will be Available to Improve FGD Efficiency Rick Beatty and Gary Hilkert of Invista told a Hot Topic audience Wednesday that the Orange, Texas plant will be starting operations in the first quarter 2011 and will be able to deliver dibasic acid (DBA) to the power market. The meeting started with an overview by McIlvaine pointing out that the PM2.5 ambient rules will force states to require very low emissions of SO2 in order to reduce sulfates. Los Angeles is still struggling to meet the ambient rules even after they eliminated coal-fired power plants and major sources. The South Coast Air Quality Management District issued a new rule this month which will require refineries and several remaining sources to reduce SO2 to less than 10 tons at a cost of many millions of dollars. Note this is not 10,000,000 tons, or 10,000 tons. It is 10 tons aggregated for all sources. By contrast coal-fired boilers in the rest of the country emit 8.9 million tons. The new South Coast reduction is less than CEMS accuracy when the emissions are 10,000 tons. There is a caveat. If sources cannot buy allowances for less than $50,000/ton, then there is some relief. Welcome to the new world of PM2.5 ambient limits. DBA can substantially improve the efficiency of a limestone SO2 scrubber. In fact it can provide the equivalent of spraying an extra 20 gpm/1000 cfm of limestone slurry. So a power plant with the need to move from 92 to 95 percent SO2 removal can either add 25 percent to the pump energy input or buy an organic chemical. With greenhouse gases being of increasing concern, the increase in energy consumption is critical. DBA can minimize the efficiency reduction due to high chlorides in the recirculating scrubbing liquor. It can provide fuel and limestone purchasing flexibility. There is the potential to add to the biological oxygen demand in the wastewater but zero liquid discharge or biological treatment solves this problem. Most plants have wastewater concerns with or without DBA. DBA may improve HCl removal efficiency. Its function in dissolving the limestone should be equally effective on acid gases other than SO2. Since the Utility MACT will probably limit HCl to 3 ppm, it is likely that scrubber systems will be designed around this parameter. Invista is offering carload quantities of DBA for testing.

Fabric Selection for Coal-fired Boilers Webinar - Hot Topic Hour October 28, 2010
A large group of attendees heard five very good presentations related to the selection of the best filter media to meet the various coming regulations for PM2.5. Attendees agreed that the fundamental filtration capability of the vast majority of fabrics available today, as measured by laboratory tests, far exceeds any existing or expected emission control requirement and the performance of many is below the minimum detectable limit of the test methods. Several presenters pointed out that while the results of these evaluations can be a good guide for filter efficiency and pressure drop, the actual performance of filter material will rarely achieve the levels seen in these tests. This is because the actual performance is dependent on many factors related to the specific site conditions. This causes a concern in the industry that regulators will assume that lab test results are indicative of actual performance and expect the same performance at every installation. Dr. McKenna indicated that because filter media performance was so good, future enforcement will most likely be focused on plant baghouse O&M. He also stated that it will be important to demonstrate what aspects of O&M plans are practical and valuable, so that regulators do not make these plans an operational nightmare.

Catalyst Selection for Coal-fired Power Plants Webinar - Hot Topic October 21, 2010
Experts representing consulting, catalyst, regeneration, and systems companies provided an indepth analysis of the latest trends in catalyst use in coal-fired power plants. The dominant theme was that the SCR is no longer just a NOx removal device but is a multi-pollutant control device. Various alternatives for increasing performance and decreasing cost were proposed. Some involved maintenance of the existing catalyst while others emphasized better designs which last longer without maintenance and can thereby minimize or eliminate the maintenance. There was also discussion on how the various designs compare. The claim was made that hydraulic diameter was a better measure than pitch. There was agreement that it would be desirable to define various terms relative to maintenance of catalysts. The consensus seemed to be as follows: CATALYST Management 1. Maintenance a. Cleaning b. Rejuvenation c. Regeneration 2. Replacement Cleaning Catalyst: a dry process such as vacuum or mechanical removal of accumulations Rejuvenation Catalyst: wet chemical removal of accumulations Regeneration Catalyst: wet chemical removal plus re-impregnation of catalytic compounds Physical characteristics 1. Geometry a. Catalyst shape 1. Honeycomb 2. Corrugated 3. Plate b. Openings 1. Pitch 2. Hydraulic diameter Hydraulic diameter: The hydraulic diameter, DH, is a commonly used term when handling flow in noncircular tubes and channels. Using this term one can calculate many things in the same way as for a round tube. Definition: DH =4A P where A is the cross sectional area and P is the wetted perimeter of the cross-section. Reference http://en.wikipedia.org/wiki/Hydraulic_diameter McIlvaine solicits the input from subscribers as to the appropriate nature of this classification.

Robert (Bob) Fraser, QEP, a Senior Technical Director for Power Generation Services within AECOM Environment, believes the proposed Boiler MACT is a prequel to the Utility MACT. Since the best utility units are better controlled than their industrial counterparts he expects a more stringent utility rule. If low CO levels are required because CO is a surrogate for organic HAPs then there may be a problem meeting NOx limits. Oxidation catalysts have not been proven for solid fuel applications with the possible exception of the Babcock regenerative catalyst for wood-fired boilers. Incinerators control dioxins using ACI, but with lower quantities of dioxinsit may be hard for the utility industry to achieve comparable percent efficiencies.
