First-year's operation of a full-scale second-generation FBC in an industrial plant

Conference ·
OSTI ID:6262072
Data related to the operation of a two stage coal fired fluidized bed boiler installed for Iowa Beef Processors, Inc. Amarillo, Texas are presented. This steam generator, which has a rating of 70,000 lb/hr steam, 650 psig, is the large privately funded fluidized bed coal combustion installation in the United States. The facility includes a dual bed combustor, whereby the coal is burned in a lower bed containing steam tubes and sulfur dioxide is collected in an upper bed containing dolomite. Coal burns predominantly in the lower bed at relatively high temperatures while combustion is completed in the upper bed. The upper bed also improves sulfur capture by reacting with SO/sub 2/ generated in the freeboard, which would be difficult to capture in early designs for FBC packaged boilers. The two stage concept provides high combustion efficiency, low NO/sub X/ emissions, and high sulfur capture. The results of recent measurements of emissions of sulfur dioxide will be included in this presentation. 4 figures.
