Engineering development of coal-fired high-performance power systems. Technical progress report 2, October--December 1995

In Phase 1 of the project, a conceptual design of a coal-fired high performance power system was developed, and small scale R and D was done in critical areas of design. The current Phase of the project includes development through the pilot plant stage, and design of a prototype plant that would be built in Phase 3. The power generating system being developed in this project will be an improvement over current coal-fired systems. Goals have been identified that relate to the efficiency, emissions, costs and general operation of the system. These goals are: Total station efficiency of at least 47 percent on a higher heating value basis; emissions: NO{sub x} < 0.06 lb/MMBtu, SO{sub x} < 0.06 lg/MMBtu, and particulates < 0.003 lb/MMBtu; all solid wastes must be benign with regard to disposal; over 95% of the total heat input is ultimately from coal, with initial systems capable of using coal for at least 65% of the heat input; and ten percent lower cost of electricity (COE) relative to a modern coal-fired plant conforming to NSPS
