A plant owner opting to build a new coal-fired facility has several processes from which to choose. Among the most common are the spreader-stoker- and the pulverized-coal-fired boiler. Since pollution control is now an integral part of any coal-fired operation, fluidized-bed combustion (FBC) is becoming increasingly popular. Reason: This process does not require auxiliary equipment to control SO/sub 2/. Comparing the operation and economics of four coal-burning processes can help make this selection a somewhat easier one. This analysis examines four types of combustion: spreader stoker, pulverized coal, bubbling fluidized bed, and circulating fluidized bed. The descriptions are for a 200,000-lb/hr unit operating under like conditions.
