摘要

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(sub 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(sub 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(sub 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(sub 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(sub 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(sub x) burners (LNB) retrofit resulted in a NO(sub 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(sub x) and LOI emissions.
