Coal reburning for cyclone boiler NO{sub x} control demonstration. Quarterly report No. 13, April--June 1993
The coal reburning for cyclone boiler NO{sub x} control system consists of commercially available equipment, such as a pulverizer, burners, a pneumatic coal transfer system, overfire air ports and a control system, all of which are well proven, reliable equipment that can be readily installed. Extensive power plant modification is not required to implement the reburn technology which will increase the potential for commercialization. The coal reburning technology will be a desirable alternative for cyclone boiler NO{sub x} control by offering: (1) A technically and economically feasible low-NO{sub x} alternative for cyclone boilers to achieve a 50% to 60% NO{sub x} reduction where one currently does not exist. (2) Significant reductions in emission-levels of oxides of nitrogen achieved at a low capital cost and very low operating costs (compared to the SCR technology). (3) No need for a supplemental fuel. Reburn will be carried out using the present boiler fuel which is coal. (4) A system that will maintain boiler reliability, operability, and steam production performance after retrofit. The coal reburning for cyclone boiler NO{sub x} control demonstration project will be carried out at the Nelson Dewey Station Unit No. 2 of Wisconsin Power and Light in Cassville, Wisconsin.
