Book excerpt: The objective of this project is to demonstrate on a commercial scale several innovative applications of cost-reducing technology to the Chiyoda Thoroughbred-121 (CT-121) process. In both greenfield and retrofit situations demonstrations of the following innovative design approaches will further reduce the cost and provide a clear advantage to CT-121 relative to competing technologies. Use of fiberglass reinforced plastic (FRP) to construct the absorber vessel, wet ducts, and chimney (stack), elimination of flue gas reheat, elimination of the spare absorber, and use of a single vessel for simultaneous particulate and SO2 removal. The demonstration will be performed at Georgia Power Company's Plant Yates Unit No. 1 (100 MW capacity) near Newman, Georgia. The project is being conducted in the following three phases: Phase 1 -- Permitting and Preliminary Engineering; Phase 2 -- Detailed Engineering, Construction, and Startup; and Phase 3 -- Operation, Testing and Disposition. Since April, all environmental permits and FAA approvals have been granted by the issuing authorities with the exception of the gypsum stack design and operating plan permit which is expected within the next 60 days. Phase 2 activities reached a peak during the April--June quarter as major components were fabricated and delivered to the site. Internal installation and finishing work continues on Jet Bubbling Reactor while the Fiberglass-Reinforced Plastic chimney only lacks the last few support steel pieces to be complete. Concrete work continues, including containment sumps, ball mill foundation and duct supports. The limestone slurry tank has been finished and acoustically tested but will require additional work on the floor before it will be acceptable. Also, a mechanical contractor has been selected and should begin work in August. There have also been numerous visitors to the site from the Southern Company, DOE, EPRI, Bechtel and Chiyoda. 1 fig.

Book excerpt: This report presents results from the third phase of an Innovative Clean Coal Technology (ICC-1) project demonstrating advanced tangentially-fired combustion techniques for the reduction of nitrogen oxide (NO(subscript x)) emissions from a coal-fired boiler. The purpose of this project was to study the NO(subscript x) emissions characteristics of ABB Combustion Engineering's (ABB CE) Low NO(subscript x) Concentric Firing System (LNCFS) Levels I, II, and III. These technologies were installed and tested in a stepwise fashion at Gulf Power Company's Plant Lansing Smith Unit 2. The objective of this report is to provide the results from Phase III. During that phase, Levels I and III of the ABB C-E Services Low NO(subscript x) Concentric Firing System were tested. The LNCFS Level III technology includes separated overfire air, close coupled overfire air, clustered coal nozzles, flame attachment coal nozzle tips, and concentric firing. The LNCFS Level I was simulated by closing the separated overfire air nozzles of the LNCFS Level III system. Based upon long-term data, LNCFS Level HI reduced NO(subscript x) emissions by 45 percent at full load. LOI levels with LNCFS Level III increased slightly, however, tests showed that LOI levels with LNCFS Level III were highly dependent upon coal fineness. After correcting for leakage air through the separated overfire air system, the simulated LNCFS Level I reduced NO(subscript x) emissions by 37 percent. There was no increase in LOI with LNCFS Level I.

Book excerpt: This quarterly report discusses the technical progress of a U.S. Department of Energy (DOE) Innovative Clean Coal Technology (ICCT) Project demonstrating advanced tangentially-fired combustion techniques for the reduction of nitrogen oxide (NOx) emissions from a coal-fired boiler. The project is being conducted at Gulf Power Company's Plant Lansing Smith Unit 2 located near Panama City, Florida. The primary objective of this demonstration is to determine the long-term effects of commercially available tangentially-fired low NOx combustion technologies on NOx emissions and boiler performance. A target of achieving fifty percent NOx reduction using combustion modifications has been established for the project. The stepwise approach that is being used to evaluate the NOx control technologies requires three plant outages to successively install the test instrumentation and the different levels of the low NOx concentric firing system (LNCFS). Following each outage, a series of four groups of tests are performed. These are (1) diagnostic, (2) performance, (3) long-term, and (4) verification. These tests are used to quantify the NOx reductions of each technology and evaluate the effects of those reductions on other combustion parameters such as particulate characteristics and boiler efficiency. During this quarter, tests of the LNCFS Level III system were conducted to determine the effect that fuel fineness has on NOx emissions and unburned carbon levels. Results showed that changing the fineness of the fuel has almost no effect on NOx emissions; however, unburned carbon levels can be reduced significantly by increasing fuel fineness.

Book excerpt: The primary goal of this project is the characterization of the low NO(subscript x) combustion equipment through the collection and analysis of long-term emissions data. The project provides a stepwise evaluation of the following NO(subscript x) reduction technologies: Advanced overfire air (AOFA), Low NO(subscript x) burners (LNB), LNB with AOFA, and Advanced Digital Controls and Optimization Strategies. The project has completed the baseline, AOFA, LNB, and LNB+AOFA test segments, fulfilling all testing originally proposed to DOE. Analysis of the LNB long-term data collected show the full load NO(subscript x) emission levels to be near 0.65 lb/MBtu. This NO(subscript x) level represents a 48 percent reduction when compared to the baseline, full load value of 1. 24 lb/MBtu. These reductions were sustainable over the long-term test period and were consistent over the entire load range. Full load, fly ash LOI values in the LNB configuration were near 8 percent compared to 5 percent for baseline. Results from the LNB+AOFA phase indicate that full load NO(subscript x) emissions are approximately 0.40 lb/MBtu with a corresponding fly ash LOI value of near 8 percent. Although this NO(subscript x) level represents a 67 percent reduction from baseline levels, a substantial portion of the incremental change in NO(subscript x) emissions between the LNB and LNB+AOFA configurations was the result of operational changes and not the result of the AOFA system. Phase 4 of the project is in progress. During first quarter 1995, design of the advanced control and optimization software and strategies continued. Process data collected from the DCS is being archived to a server on the plant information network and subsequently transferred to SCS offices in Birmingham for analysis and use in training the neural network combustion models.

Phase 4 of the project, demonstration of advanced control/optimization methodologies for NO(subscript x) abatement, is now in progress. The methodology selected for demonstration at Hammond Unit 4 is the Generic NO(subscript x) Control Intelligent System (GNOCIS), which is being developed by a consortium consisting of the Electric Power Research Institute, PowerGen, Southern Company, Radian Corporation, U.K. Department of Trade and Industry, and U.S. Department of Energy. GNOCIS is a methodology that can result in improved boiler efficiency and reduced NO(subscript x) emissions from fossil fuel fired boilers. Using a numerical model of the combustion process, GNOCIS applies an optimizing procedure to identify the best set points for the plant on a continuous basis. GNOCIS is in progress at Alabama Power's Gaston Unit 4 and PowerGen's Kingsnorth Unit 1. The first commercial demonstration of GNOCIS will be at Hammond 4.

Book excerpt: The project's objective is to demonstrate innovative applications of technology for cost reduction for the Chiyoda Thoroughbred-121 (CT-121) process. The CT-121 process is a wet FGD process that removes SO2, can achieve simultaneous particulate control, and can produce a salable by-product gypsum thereby reducing or even eliminating solid waste disposal problems. Figure 1 shows a flow schematic of the process. CT-121 removes SO2 and particulate matter in a unique limestone-based scrubber called the Jet Bubbling Reactor (JBR). IN the JBR, flue gas bubbles beneath the slurry, SO2 is absorbed, and particulate matter is removed from the gas. The agitator circulates limestone slurry to ensure that fresh reactant is always available in the bubbling or froth zone sot that SO2 removal can proceed at a rapid rate. Air is introduced into the bottom of the JBR to oxidize the absorbed SO2 to sulfate, and limestone is added continuously to neutralize the acid slurry and form gypsum. The JBR is designed to allow ample time for complete oxidation of the SO2, for complete reaction of the limestone, and for growth of large gypsum crystals. The gypsum slurry is continuously withdrawn from the JBR and is to be dewatered in a gypsum stack. The stacking technique involves filing a diked area with gypsum slurry, allowing the gypsum solids to settle, and removing clear liquid from the top of the stack for recycle back to the process.

Book excerpt: This Phase 3A test report summarizes the testing activities and results for the third testing phase of an Innovative Clean Coal Technology (ICCT) demonstration of advanced wall-fired combustion techniques for the reduction of nitrogen oxide (NO(subscript x)) emissions from coal-fired boilers. The project is being conducted at Georgia Power Company's Plant Hammond Unit 4 located near Rome, Georgia. The primary goal of this project is the characterization of the low NO(subscript x) combustion equipment through the collection and analysis of long-term emissions data. Described in this report are the test plans, data measurements, and data analyses performed during the Phase 3A effort. The present report also contains sufficient background material to provide an understanding of the overall program scope, the relationship of Phase 3A to the overall program, the testing methodologies, testing procedures, and unit configuration. Results from 66 short-term tests indicate increasing NO(subscript x) emissions over the load range ranging from 0.5 lb/MBtu at 300 NM to around 0.65 lb/MBtu at 480 MW. Fly ash loss-on-ignition (LOI) for these loads ranged from 5.4 to 8.6 percent. Long-term test results indicated high load (480 MW) NO(subscript x) emissions of approximately 0.65 lb/MBtu. At the 300 MW mid load point, the emissions dropped to 0.47 lb/MBtu which is slightly lower than the 0.50 lb/MBtu shown for the short-term data. The annual and 30-day average achievable NO(subscript x) emissions were determined to be 0.55 and 0.64 lb/MBtu, respectively, for the load scenario experienced during the Phase 3A, long-term test period. Based on the long-term test results for Phase 3A, at full-load the low NO(subscript x) burners (LNB) retrofit resulted in a NO(subscript x) reduction of 48 percent from baseline, while at 300 MW the reduction was approximately 50 percent. A series of tests was also conducted to evaluate the effects of various burner equipment settings and mill coal flow biasing on both NO(subscript x) and LOI emissions.
