This paper discusses a current research and development program whose object is to advance the technical readiness of large, coal-fired heaters to supply the input to closed-cycle gas turbine cogeneration systems. Such closed-cycle systems become increasingly attractive as energy cost increase. The gas turbine working fluid is completely isolated from the products of coal combustion, thus avoiding corrosion and erosion of the gas turbine system. Additionally, the nature of the thermodynamic cycles is frequently such as to afford substantial savings in coal input requirements as compared to steam turbine based systems producing equivalent process heat and power. This paper describes three fired heater concepts that are under development for CCGT service. The organization of the research and development program, and the development needs of the fired heaters that are to be satisfied by the R&D program, are discussed.
