Abstract |
The report describes a demonstration of reburning on a cyclone-fired boiler. The project included a review of reburn technology, aerodynamic flow model testing of reburn system design concepts, design and construction of the reburn system, parametric performance testing, long-term load dispatch testing, and boiler tube wall thickness monitoring. The report also contains a description of Ohio Edison's Niles No. 1 host unit, a discussion of conclusions and recommendations derived from the program, and tabulations of data from parametric and long-term tests. A primary focus of the report was to document performance of the Niles Unit No. 1 when employing natural gas reburning, but it was equally as important to be able to use the information to make technical and economic judgements on the application of natural gas reburning to the entire family of cyclone boilers. Performance of the reburn system at Niles might not represent the highest nitrogen oxide (NOx) reduction possible on cyclone boilers because of differences in design and operating parameters, including boiler size and mode of operation (e.g., cyclic vs base-loaded). |
