Fully Automating HRSG Feedwater Pumps
Even a relatively simple start-up process can have many steps and delays for operator cross-checks. Automation can simplify the procedure for the operator while reducing start-up time. In addition, more sophisticated controls techniques may be applied to improve process stability, reduce energy usage, and increase operating flexibility. Modern distributed control system (DCS) platforms offer capabilities that were unavailable just a few years ago. Features such as integrated graphical engineering environments, simplified sequencing controls, and improved human-machine interfaces (HMI) make higher levels of automation more practical from the standpoints of implementation, maintenance, and ease of use. The timing of these advances couldn’t be better—critical operating personnel throughout the power industry are approaching retirement age, and there are insufficient numbers of skilled younger personnel to replace them. Leveraging the existing plant knowledge base to design automation that reduces the burden on plant operators will be essential to meeting tomorrow’s plant demands. As an example, the following case study describes automating a simplified feedwater system for a combined-cycle power plant. The existing legacy DCS controls are proven and reliable; however, the sequence of operations and coordination of regulatory controls is not automated, therefore, it requires a high degree of knowledge and attention on the part of the operator. This case study describes a combination of controls automation strategies and HMI techniques designed to increase the overall level of automation while improving ease of use by operators and maintenance personnel.

Data Centers will Consume 8% of Worlds Energy in 2020
The rapid increase in cloud-scale services is driving a growth in data centers. Resources and support-infrastructures inside these centers consume a lot of energy. It is estimated that, currently, data centers consume about 3% of the world’s electricity production [1] and should double in every 5 years [2]. By 2020, data centers should consume approximately 8% of the total world’s energy [3] and emit 340 metric megatons of CO2 annually [4]. Data centers in the U.S. consumed 2% of all electricity usage in 2010 [9]. Utility, as a primary source, provides electricity for data centers. Diesel and natural gas generators are employed as emergency sources during a utility power outage. Since coal and gas plants are the dominant sources of the electricity produced in the U.S., the current growth in data centers energy consumption will produce large carbon emission and incur high electricity cost. Environmental concerns, as well as energy prices, obligate companies to build green data centers, which partially or completely use renewable energy sources, such as wind and solar. Incorporating renewable sources can reduce carbon footprint, energy price, and loss, but their intermittent nature is a key challenge. New generation of data centers will be either own renewable energy sources or buy it directly from an existing off-site generation (co-location). More importantly, they will play an active role instead of being a pure consumer to the utility.

The Electrical Generating Systems Association (EGSA) is the world’s largest organization exclusively dedicated to on-site power generation. It has rated silencers into 7 classes. Generally silencers are one of or a combination of three types of devices: 1.Reactive silencers, often referred to as "chamber" silencers, generally have their peak DIL in the 63 or 125 Hz OBCF 2.Absorptive silencers, often referred to as "packed" silencers, generally are most effective in the 250 Hz through 8 KHz OBCFs. 3.Resonators are generally specifically designed to have an effective DIL over a very narrow range, usually no more than a single octave. Reactive Silencers are thought of as Exhaust Silencers and their performance is usually based on a "typical" Exhaust Gas Temperature (EGT) value. Generally Absorptive Silencers are applied as intake silencers to best control the high frequency content of modern high speed turbocharged engines. When absorptive are applied in combination with a reactive silencer, as is becoming more common with higher speed multi-cylinder engines and requirements for noise reduction as an A-Weighted value are becoming more demanding, the performance of these must be adjusted for size and the longer wavelengths for specific frequencies in the exhaust system. Generally a Resonator is designed for a specific requirement.

Gut Rehab Turns South Jersey Cogen Plant into Electricity Market Gem
Five years of essentially no maintenance investment or capital improvement at the Eagle Point Power Generation facility in Westville, NJ, had clearly taken its toll by the time Rockland Capital acquired the facility in April 2012. Today, Eagle Point expects the plant capacity factor to approach 50% once the last of the capital improvements are finished. Those improvements include everything from a punch list of 146 maintenance activities as well as capital upgrades, including a new steam turbine/generator, wet compression and fogging, and a complete gas turbine optimization and augmentation package which helped avoid the $11-million cost of an SCR.

The Power of Flexibility: Turbine Inlet Air Chilling Benefits
Gas turbines are constant volume air intake machines; consequently, air mass flow and resultant power output fall as ambient temperatures rise and air density falls. The purpose of Turbine Inlet Air Chilling (TIAC) is to restore the power output of a combustion turbine at elevated ambient temperatures to its rated capacity or better. As the critical 'operating system' of the TIAC enhancement, the control technology also plays an integral role in maximizing operational flexibility.

The Value Proposition Offered by HEPA Filtration
The cost of an E12 HEPA filter may be as much as four or five times the price of a conventional air filter. Economic analyses conducted by owners have typically focused on compressor performance and assumed a one- to two-year lifetime for HEPAs serving high-hours engines. Based on those parameters alone the HEPA was, and continues to be, a tough sell. But where the cost of replacement power is expensive or unavailable, water washing is not feasible, or a corrosive ambient environment is causing premature engine failure, HEPA filtration may be readily justified.

Desuperheating Valves Take the Heat
A cascading bypass system uses an high pressure (HP) steam bypass valve and a hot reheat (HRH) steam bypass valve to manage steam flow to the steam turbine. The HRH bypass valve actuator determines the valve’s ability to respond to system demands. This article discusses the selection of HRH valves and actuators, and the corresponding impact on other plant components.

Gas Turbine Combined Cycle Fast Start: The Physics Behind the Concept
GTCC startup optimization is essentially minimizing the time required to reach the dispatch power (e.g., full load or a specific part load) without "breaking anything" in the process. For example, failure to control thermal stresses results in cracks via low/high cycle fatigue (LCF and HCF) and brittle fracture. This article provide relevant and easy-to-use technical information (in the form of simple charts, basic equations and representative physical quantities) to form an informed opinion on available technologies for GTCC startups.

Cost Benefits of Critical Valve Repair in the Heat Recovery Steam Generator
Modern advance frame combined-cycle power facilities operate in a dispatch environment where cold starts, accelerated ramp rates and low load conditions are the norm and where Balance of Plant (BOP) equipment accounts for more than half of all forced outages. An analysis by Pentair revealed that valves are a significant contributing factor in forced outages, primarily based on their application numbers and the severity of their service applications. This article focuses on small bore vent valves and drain valves, reporting research findings that repairing these valves is more prudent and economical than replacing them.

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.

Continuous-Blowdown Block Valve Reduces Startup Time
At Essential Power LLC’s Newington Energy Facility, the high-pressure (HP) steam-drum continuous blowdown system was designed to cascade flow to the intermediate-pressure (IP) steam drum. While the valve worked well for controlling flow, it did not have the degree of leak-tightness required for stopping flow from the drum during typical overnight shutdowns. An automatic full-port ball valve was installed upstream from the existing automatic control valve to eliminate the risk of flashing.

Converting from Hydraulic to All-Electric Gas Control Valves Benefits Frame 6 Owners
Young & Franklin valves have been in use on Frame 6 gas turbines for a decade. One advantage of an all-electric control valve is that it eliminates varnish issues by eliminating the control oil required by hydraulic actuators. Plus, electric valves are more responsive than hydraulically operated valves, have greater range, are easier to maintain, and enhance plant safety.

Electric Fuel Control Valve Streamlines Plant Operations
A Frame 6B-powered cogen plant in California was plagued with fuel-gas valve problems, usually requiring at least a man-shift’s worth of work each outage to disassemble, clean seats/plugs, and reassemble. One solution is to reheat the fuel gas to above the dew point (120-130F) in between the valves, but this is considered far from ideal. The better solution proved to be replacing the original valve with a “smart” electric control valve in the same location as the original and a separate solenoid-operated stop/isolation valve about 6 ft upstream—just outside and below the turbine enclosure.

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.

VFD at the Hainan Yangpu 220 MW GTCC
This paper discusses the application of variable frequency drives (VFD) in the high-pressure water feeding system of boilers serving Units 11 through 13 of a combined cycle section of the Hainan Yangpu Thermal Power Plant. The article is written by the plant engineer responsible for the operation and maintenance of the system. In the first year of operation there were severe problems with the valve caused in part by inability to measure the outlet pressure of the BFP system and it was determined that a solution lay with replacing the hydraulic coupling with VFD.

The reducing environment produced by oxygen scavengers initiates and propagates flow-accelerated corrosion (FAC) in the feedwater system and other components of high-pressure steam generators, including heat recovery steam generators (HRSGs). Since 1986, FAC-induced attack has caused numerous failures, some with fatalities, at a number of power plants in the U.S. Yet, specifications for many new power plants both domestically and globally, and in which the condensate/feedwater system contains no copper alloys, continue to call for oxygen scavenger feed to the condensate. This document is a response to this misguided trend.

Sky-vent system from Emerson insures temperature control of turbine during startup
Valves within the sky vent system of a combined cycle plant serve one of the more important control functions. During initial operation of the HRSG, these valves bypass steam (HP/HRH/LP) around the steam turbine to ensure that the unit doesn't come up to temperature too quickly. This is done as the process lines are warmed prior to admitting steam through the turbine bypass valves that dump to the condenser.

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.

Improved Reliability of High-AVT (High-pH Water Treatment) Application to Combined Cycle Plants
Generally in the water treatment of combined cycle plants, ammonia and hydrazine are used in the feedwater system and phosphates are used in the boiler system. However, in Mexico, the Tuxpan No. 2 and No. 5 power plants have adopted “High-AVT (high-pH water treatment),” in which ammonia is used to set the pH of feedwater higher than the conventional level, requiring no phosphates in the boiler system. In response to such good operational results, MhI introduced high-AVT as an option for the water treatment of combined cycle plants.

Cost and Value of Water Use at Combined-Cycle Power Plants
This study compared water requirements, plant and cooling system capital and operating costs, and plant output and efficiency between plants equipped with wet and dry cooling. Comparisons were made for 500 MW, gas-fired, combined-cycle power plants at four sites, typical of environmental conditions in California. Results of the analysis include: • the use of dry cooling reduces plant water requirements by approximately 2,000 to 2,500 acre-feet per year, • The associated costs are: − increased plant capital cost of approximately $8 million to $27 million, or about 5% to 15% of the total plant cost, − potential reduction of energy production by about 13,000–56,000 megawatt hours (MWh) per year (1% to 2% of the total), − capacity reduction on hot days of 13 to 23 MW (4% to 6% of total), and − potential annual revenue reduction of about $1.5 to $3.0 million (1% to 2% of total)

Don't Let Startup Emissions Slow You Down
In a Power Enginerring article, the authors point out that new combustion turbine (CT) simple and combined-cycle plants face new challenges in permitting because of more stringent startup emission limits. Recent permits issued in a variety of jurisdictions have included limits on startup emissions, both in mass per start and rolling annual startup mass limits for VOC, NOx and CO. The increased use of heavy duty/frame CTs for peaking applications create additional challenges. Startup and shutdown durations and emissions rates vary widely depending on CT model and other plant equipment and design choices.

Engineered solution improves SCR performance significantly
Getting gas-turbine inlet air and exhaust gas to flow where and how you want it to in powerplant ductwork is akin to herding cats. The problem, as described by industry veterans Jim Carlton, president, Granite Ridge Energy LLC, and Larry Hawk, plant engineer, Granite Ridge Energy, operated by NAES Corp, was that the plant had been challenged by an underperforming NOx catalyst since commissioning. However, routine destructive sampling of the catalyst showed reactivity at or above expectations. And testing confirmed that the ammonia injection grid was properly balanced. What to do?

AIG Tuning, Catalyst for Life Forecasting
Many gas-turbine “bubble” units installed between 2000 and 2004 are operating with their original charge of SCR catalyst. These units have outlived the original catalyst warranty (typically three years) and have benefitted from a combination of conservative design and good luck. However, as these systems reach the decade mark, the design margins have diminished because of gradual (and inevitable) deactivation of the catalyst with age. As the catalyst nears its end of life, ammonia slip begins to increase exponentially. There are practical steps operators can take to avoid this scenario.

Planning Upgrades: Evaluate the Regulatory Impacts of Upgrades Before you Buy
One ongoing study at NV Energy involves identifying possible upgrades for existing assets. Staff Engineer Susan Hill says that no particular upgrade can be applied across the utility’s fleet due to differences in regulatory requirements. For example, about three-quarters of NV Energy’s capacity is in southern Nevada, specifically Clark County; most of the remainder is in northern Nevada, relatively close to Reno. Some Clark County assets are in PM10 non-attainment areas; plus, ozone rules are not well defined for the county going forward. Northern plants are in an attainment area.

HEPA an Alternative to Compressor Washing
About 10 manufacturers are actively pursuing GT owner/operators for their replacement filter business. But only W L Gore & Associates Inc, Elkton, Md, seems focused on HEPA filters at present. Perhaps the others believe the cost hurdle is too difficult to overcome: Turbine air filters often are considered a commodity with price the deciding factor in the selection process. Gore says its filter media offers a significantly lower pressure drop and longer effective lifetime than competitors’ products.

How to Reduce Catalyst Lifecycle Cost, Improve Reliability
Balancing the requirements of each SCR system in the fleet can be challenging. A system can reduce NOx by greater than 95%, but when the efficiency of the SCR is pushed beyond 85% and—or, if—the outlet emissions are less than 5 ppm, the system becomes much more sensitive to several independent system parameters. These include overall catalytic potential, effective ammonia injection/mixing in the flue-gas stream, flue-gas characteristics for inlet NOx, velocity, and temperature distributions.

Vokes recommends combining coalescer and pre filter
In locations with high levels of atmospheric moisture (such as Northern Europe, equatorial or coastal sites), a coalescer protects against water and is typically followed by coarse and fine dust filter stages. This coalescer stage usually consists of a bank of G3 or G4 glass fibre pads treated with a water resistant coating. Such elements retain moisture well, but can quickly become clogged at higher air flows and as they become dirty, choking the air flow and raising differential pressure. Now, thanks to developments in media technology, a handful of products are available that offer an alternative approach by combining the water coalescer and pre-filter stages into one-unit.

Chillers using waste heat can reduce gas turbine fuel consumption per MW while boosting output. Barry Kellar, President of Freudenberg Filtration - North America, was the speaker in a recorded McIlvaine InterWEBview on “Sustainability.” Part of this presentation is devoted to the Villedon eee.sy or energy efficiency enhancement system. Fruedenberg not only furnishes the gas turbine inlet filters but also the cooling of the air entering the turbine based on vapor absorption technology. Waste heat from the system is used as the energy source, so capacity increases of up to 22 percent are achieved without parasitic power consumption. Barry was one of the keynote speakers at Filtration 2010 in Philadelphia. Freudenberg was one of the exhibitors along with a number of other companies familiar to the power industry.
