Combined steam and gas turbine plant and method of operation

Patent ·
OSTI ID:6768114
Steam and gas turbines share a common heat source according to the invention. A fluidized bed combustion chamber provides hot gas for the gas turbine and a heat source for a gaseous heat exchange medium which transfers heat to the steam turbine. Air flow from the gas turbine compressor is used to help control the temperature of the hot gases in the fluidized bed and may also be used as the heat exchange medium for the steam turbine. Controls for air flow and pressure are provided to accommodate variations in power demand. A method of operating such a plant is also disclosed.
