CONCEPTUAL DESIGN OF CLOSED BRAYTON CYCLE FOR COAL-FIRED POWER GENERATION.

The objectives to be realized in developing a closed cycle gas turbine are: (1) to exploit high temperature gas turbine technology while maintaining a working fluid which is free from combustion gas contamination. (2) to achieve compact turbo-equipment designs through pressurization of the working fluid. (3) to obtain relatively simple cycle configurations. The technical/economic performance of a specific closed cycle gas turbine system was evaluated through the development of a conceptual plant and system design. This energy conversion system is designed for electric utility service and to utilize coal directly in an environmentally acceptable manner.
