One technology with high potential for meeting the end-of-century requirements for large power generation applications is combined-cycle pressurized fluidized bed combustion (PFBC). PFBC permits the combustion of a wide range of coals, including high sulfur coals, with a sorbent, such as limestone or dolomite, in a fluidized bed combustor at an elevated pressure. The sorbent captures most of the sulfur emissions during the combustion process itself which greatly reduces or completely eliminates the need for expensive downstream sulfur control equipment. PFBC produces a dry solid sorbent waste which is easily disposed of in an environmentally acceptable manner. In addition, the lower operating temperature substantially reduces nitrogen oxide emissions. In addition to these environmental features, PFBC components and plant facilities are considerably smaller than nonpressurized or conventional units of equal generating capacity. To further the development of PFBC, the Department of Energy and Ohio Power Company (OPCo), a wholly owned subsidiary of American Electric Power Company, Inc. (AEP), have negotiated a Cooperative Agreement to construct and operate a 70 megawatt (MWe) PFBC combined-cycle demonstration plant. The work to be performed under the Cooperative Agreement covers the design, construction, and operation of the demonstration plant. The overall objective of this project is to demonstrate PFBC technology at a large scale for use in commercial electric generating plants. The specific goal of this project is to demonstrate that combined-cycle PFBC technology is a cost-effective, reliable, and environmentally superior alternative to conventional coal fired electric power generation with flue gas desulfurization.
