Closed Gas Turbine Heater program. Third quarterly technical progress report, October 3, 1977--December 31, 1977

Progress is reported in a program intended to advance high-temperature closed gas turbine power conversion systems to a point of technological readiness for use in coal-fired public utility power conversion plants. The initial contract addresses two specific problem areas. These are: the identification and analysis of system concepts which offer highest overall plant efficiency consistent with lowest cost of electricity (COE) from coal-pile-to-bus-bar; and the identification and preliminary design of combuster/heat exchanger concepts compatible for use as the cycle gas primary heater for those plant systems.
