This report covers work carried out under Task 2, Concept Definition and Analysis, and Task 3, Preliminary R and D, under contract DE-AC22-92PC91155, ``Engineering Development of a Coal Fired High Performance Power Generation System`` between DOE Pittsburgh Energy Technology Center and United Technologies Research Center. The goals of the program are to develop a coal-fired high performance power generation system (HIPPS) by the year 2000 that is capable of: > 47% thermal efficiency; NO{sub x}, SO{sub x} and Particulates {le} 25% NSPS; cost {ge} 65% of heat input; and all solid wastes benign. In order to achieve these goals our team has outlined a research plan based on an optimized analysis of a 250 MW{sub e} combined cycle system applicable to both frame type and aeroderivative gas turbines. Under the constraints of the cycle analysis we have designed a high temperature advanced furnace (FHTAF) which integrates several combustor and air heater designs with appropriate ash management procedures. The cycle optimization effort has brought about several revisions to the system configuration resulting from: (1) the use of Illinois No. 6 coal instead of Utah Blind Canyon; (2) the use of coal rather than methane as a reburn fuel; (3) reducing radiant section outlet temperatures to 1700F (down from 1800F); and (4) the need to use higher performance (higher cost) steam cycles to offset losses introduced as more realistic operating and construction constraints are identified.
