| Abstract |
Reduction of unburned carbon levels for coal burning power plants that are equipped with 10w-NOx burners decreases fuel costs, and facilitates fly ash recycling and disposal. For this purpose, Babcock and Wilcox (B&W) has developed a proprietary coal nozzle mixing device to install in commercial low-NOx pulverized coal (PC) burners. Combustion and emissions performance of a full-size, 100 million Btu/hr (MBtu/hr), DRB-XCL® 10w-NOx PC burner and the proprietary device was characterized in the Clean Environment Development Facility at B&W with four different fuels ranging from subbituminous to low volatile bituminous coals. Experimental parameters included coal fineness, excess air, and thermal load. Relative to the baseline 10w-NOx burner, the coal nozzle device produced shorter flames and lower unburned carbon levels, while maintaining low NOx emissions. Retrofit plans for commercial installations are underway. |
