Market and equipment performance analysis for the application of coal-based fuels/advanced combustion systems: Technical/economic assessment of coal-fired slagging combustors
Advanced slagging combustors were assessed for market potential and cost effectiveness as retrofits for the utility industry assuming that such slagging combustors achieve 90% ash rejection and 50% SO/sub 2/ capture, with a maximum boiler derating of 10%. A 12,000 Btu/lb design coal with a 10% ash and 3% sulfur content was utilized. The cost effectiveness of the slagging combustors was based on a four-year payback period for systems meeting emission limits of 0.03 lb of particulates/MMBtu, 0.6 lb of NO/sub x//MMBtu and 1.2 lb of SO/sub 2//MMBtu. Baghouses and dry scrubbers were used to achieve these emission limits. A market analysis identified 193 oil-fired utility installations (54,000 MW, 2.8 Quads) as potential slagging combustor conversion candidates. Four case study units were selected based on geographic distribution, range of capacities, and difference of manufacturer and firing type. This report discusses the results of these analyses.
