ABSTRACT:
A combined cycle steam and gas power plant is disclosed in which energy for generating steam to drive a steam turbine and for heating air to drive a gas turbine is provided by combustion of a single carbonaceous sulfur-bearing fuel such as coal at nearly atmospheric pressure in a sulfur-sorbing fluidized bed combustor. Fluidizing and combustion air for the combustor is furnished by exhaust from the gas turbine, and an air heat exchanger within the combustor allows indirect heating of air for driving the gas turbine so that corrosion of gas turbine hardware by the products of combustion is avoided.
