Abstract:
A Brayton and Rankine combined cycle power generation system, comprising in combination:a gas compressor having an inlet and an outlet; a combustor downstream of said compressor, said combustor having a fuel port coupled to a source of fuel, an oxidizer port coupled to said compressor outlet and an outlet port for combustion products resulting from combustion of fuel from said source of fuel with oxidizer from said oxidizer port; a turbine downstream of said combustor, said turbine having an input coupled to said combustor outlet port, an output for the combustion products entering said turbine at said input, and a power output; a heat recovery steam generator downstream of said turbine output, said combustion products at least partially routed through said heat recovery steam generator; a gas generator including an oxygen inlet, a hydrocarbon fuel inlet and a water inlet, said water inlet receiving water from a water path in said heat recovery steam generator in heat transfer contact with the combustion products from said turbine output routed through said heat recovery steam generator, such that the water entering said water inlet of said gas generator is initially heated by the combustion products from said turbine output at said heat recovery steam generator, said gas generator combusting the hydrocarbon fuel with oxygen to produce a high temperature gas including carbon dioxide and water; a bottoming cycle turbine located downstream of said gas generator and receiving the high temperature gas including carbon dioxide and water from said gas generator therein, said turbine outputting power from said system; and a condenser downstream of said bottoming cycle turbine, said condenser at least partially separating carbon dioxide from water in the gas exiting said turbine.
