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 (1) > 47% thermal efficiency; (2) NO{sub x}, SO{sub x} and particulates <25% NSPS; (3) cost {>=}65% of heat input; (4) all solid wastes benign. In order to achieve these goals, this team has outlined a research plan based on an optimized analysis of a 250 MW, combined cycle system applicable to both frame type and aeroderivative gas turbines. Under the constraints of the cycle analysis the authors have designed a high temperature advanced furnace (HITAF) which integrates several combustor and air heater designs with appropriate ash management procedures. Recent efforts in cycle optimization for focusing on various repowering designs as expanded opportunities for the HIPPS concept. After reviewing the full range of options, this analysis examines (a) windbox repowering, (b) feedwater heating repowering, and (c) full repowering. The preliminary conclusion is that the latter offers the most economic incentive. Under Task 3.1.6, the authors are investigating different approaches to waste utilization for the authors` HIPPS commercial plant design. The economic and engineering aspects of utilizing the byproducts from FGD and coal combustion ash are being reviewed. The conditions for economic use of by product gypsum are addressed and outlined in this report. The corrosion of ceramic materials by high temperature coal ash is a continuing subject of the authors` efforts. They report here some corrosion tests of four different SiC samples by both Wyodak and Illinois No. 6 ash at 1093{degrees}C and 1260{degrees}C. The results to date indicate that corrosion remains a major unsolved problem for structural ceramic materials at the extreme conditions in this plant design.
