Integration of a pressurized fluidized bed (PFB) coal combustor with a gas turbine/steam turbine combined cycle is an economic and environmentally attractive alternative to pulverized coal steam boilers and flue gas desulfurization for utility power plants burning high sulfur coal. A process by which a coal-fired, air-cooled PFBC may be integrated into a combined cycle system is presented. The process can provide a coal pile-to-busbar efficiency of approximately 40%. About one-third of the air from the gas turbine's compressor is used to fluidize the bed and support combustion, and the remaining air is indirectly heated - essentially to bed temperature - by flowing through an in-bed tubular heat exchanger. In this system, 60% of the total plant power is produced by the gas turbine and 40% is produced by the steam system.
