Assessment of integrated gasification combined cycle power generation
This paper presents the results of a comparative study of various selected technologies for coal-fired electric power generation with emphasis on the generation of power using the Integrated Gasification Combined Cycle (IGCC) Concept. All of the power plant conceptual designs were prepared as grassroots plants with a nominal output of 500 MWe, located in the east-central region of the United States. The designs were based upon a uniform set of design, performance, economic criteria and a 1990 state-of-the-art reference frame. Three IGCC power plant concepts were studied (Texaco, BGC/Lurgi, and Westinghouse gasification processes) and compared with conventional pulverized coal-fired power plants. Each of the IGCC plant concepts were designed to produce a medium-Btu fuel gas which was treated in a SELEXOL processing facility to remove sulfur from the fuel gas in order to meet NSPS SO/sub 2/ emission control requirements. The IGCC power generation facilities for each concept used advanced gas turbines with a rotor inlet temperature of 2150/sup 0/F. Conventional heat recovery steam generators produced high pressure superheated steam which was expanded through a non-reheat steam turbine exhausting to a conventional condenser. The basic designs, estimated performance, and economics for the IGCC plants are presented for both eastern and western coals with varying sulfur removals and are compared with conventional power plants of the same outputs. A consistent set of technical and economic ground rules was employed in making the comparisons. Each of the base case concepts that were studied were found to be cost competitive under the economic ground rules. 8 figures, 12 tables.
