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.

Constellation energy reduces Nox at low cost with emerson optimization system
In 2003 Constallation Energy completed a project to optimize the performance of two units at its C.P. Crane station in Baltimore, Maryland utilizing advanced neural network technology. The C. P. Crane site has two (2) units, each with four (4) Babcock &Wilcox (B&W) cyclonic furnace burners in an opposed-wall firing configuration. The NOx optimization portion of the project has provided the utility with significant reduction in the NOx emissions with a relatively small capitol investment that was recovered in the first five months of the project. This has allowed financial gains from several different aspects including the shifting of required NOx credits to other units and lowering the units’ power production costs, which has increased competitiveness in the dispatching system.

Constellation energy optimizes SNCR process with Emerson program
The SNCR optimization project at Wagner Unit #2 was coupled with the new equipment, revised operational goals, and control system revisions required for the SNCR integration and automated operation. The SNCR optimization project at Wagner Unit #2 was found to significantly decrease the NOx removal from the injection of the reagent in the furnace coupled with a new type of adaptive optimization system that significantly reduced the overall NOx emissions. This new technology eliminates manual parametric testing, and this novel feature enables a faster deployment and operational readiness than previous technology like neural network based systems. The combustion optimization system with SNCR system ON was able to reduce the NOx emissions to an average value 0.298 lb/MMBTU compared to 0.332 lb/MMBTU with optimization system off-line.

Tampa Electric installs Emerson Smart Process system to optimize NOx control with new SCR
TEC entered into a contract with Emerson Process Management Power and Water Solutions to provide an Emerson Smart process combustion optimization system on TEC Big Bend Unit #4TEC This optimization system was installed, configured, and tuned in 2007. It is an in-combustion NOx reduction process that reduces the generated NOx emissions and the cost of the SCR operation. The primary goal of this optimization system was to determine the optimal positions for various combustion parameters to achieve multiple emission goals which are defined and can be modified by the end-user. As part of this combustion optimization and SCR projects, a new CO analyzer was purchased and installed on Big Bend 4 by TEC to provide the optimization system with critical on-line feedback for status of the boiler combustion system.

Minnkota optimizes coal fired power plant to balance erratic wind generation
The ability to effectively utilize the maximum amount of the wind farm production, while preventing transmission voltage surges, was a concern for Minnkota Power Cooperative. Conversely, when the wind would slow, the conventional assets are required to respond to prevent voltage sags. Minnkota M.R.Young power station is the primary source of electric generation for more than 110,000 customers. For many years prior to the wind farm additions Young station was base-load operated to meet the generation needs of the area. The main factors requiring a revised operational mode for the plant generation are twofold. The market was being deregulated by the creation of the Midwest Independent System Operator (MISO) of the transmission grid. Also new wind farms were put into operation nearby, causing additional load demand regulation issues and voltage problems with the electrical transmission lines. The Emerson URO project required significant changes to the Young Station operations to allow Minnkota to capture available wind generated electricity by efficiently cycling the Young Station to meet constant changes in the wind generated output. The scope of the URO project was to create new fully coordinated closed loop control strategies via the following method: 1. Capture detailed unit operating data via parametric testing by cycling the units through various power ranges. 2. Using that data to develop dynamic models of the unit‟s operating characteristics at various load ranges. 3. Testing and verifying those models under actual operating conditions. 4. Modification of existing control settings and benchmarking the new strategy vs. the base strategy. The upgraded software has provided many benefits. The unit is now able to hit targeted set points accurately and with minimal megawatt overshoot, thereby contributing to reduced fuel costs. The unit is also able to ramp to the targeted set point much quicker, enabling revenue to be generated more quickly. Because the unit is able to follow load demand it is now possible for MPC to compete in the ancillary power services market. In addition, the use of optimization technology can also translate into less stress on critical equipment, further enhancing unit reliability and availability.

Neuco is now part of GE and is collaborating on advanced artificial controls to improve profitability and reduce risk. More than 120 optimization systems are in operation. Boiler Opt® consists of CombustionOpt® which optimizes fuel and air mixing and SootOpt® which dynamically directs boiler cleaning. NOx reduction from 4 to 20% is being achieved with Boiler Opt at 7 U.S. power plant boilers of 500 MW or more. Combustion opt can achieve NOx reductions of 10-15% and boiler efficiency increase of 0.5%- 1.5% with reduced opacity, better LOI and CO control. SootOpt® reduces and controls APH temperatures, reduces blowing by 10-35% and provides incremental NOx reductions of 2.5% to 5%. Zones are selected and blowers operated based model prediction and operating history. Bell River Unit 2 reduced NOx from 0.25 lbs/ mm btu to 0.20 lbs/mm btu. APS four corners use has expanded to use on all five units. CPS Energy initially installed CombustionOpt on all existing plants at Spruce and Deely and then added SootOPt. NOx at Deely is reduced from 0. 138 lbs/mmbtu to 0.112 lbs/mm btu. Xcel added boilerOpt at Tolk and Harrington and has now standardized on the program with additional installations in Minnesota and Colorado. Harrington 2 Nox reduced from 0.16 to 0.13 lbs/mmbtu ( presentation by Peter Spinney)

MPW optimizing CO and NOx with Emerson SmartProcess
MPW entered into a contract with Emerson Process Management Power and Water Solutions to provide an Emerson SmartProcess Combustion Optimization System for Muscatine Units 8 and 9 which would help reduce emissions and find the optimum positions for various parameters in the boiler combustion process Two parameters carried the highest weights in the combustion optimization system with the CO weight being about double the NOx rate which was targeted around 110 ppm with variations dependent on load. During execution of the optimization project and the first few months of operation with the CO analyzer in-service, both MPW and Emerson agreed that the most important parameter in the combustion process was CO and that it should be maintained at or below 50 ppm and if the CO limit got exceeded in the combustion process, more weight would be given to CO sacrificing NOx somewhat. However, this situation never arose during and after the project was completed. It should be noted that other than the combustion optimizer, there are no other systems post-combustion that would reduce CO. Thus, the weighting was setup to have the CO control variable carry the highest weight and NOx, the second highest. The system was satisfactorily put into operation in 2008
