Abstract:
1. A semi-closed Brayton 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 return duct downstream of said turbine, said return duct receiving at least a portion of the combustion products passing through said output of said turbine and extending to said inlet of said compressor; a gaseous oxygen duct coupled to a source of oxygen and coupled to said return duct in a manner adding oxygen to the combustion products within said return duct; and said gaseous oxygen duct located upstream of said gas compressor, such that at least a portion of the oxygen from said gaseous oxygen duct enters said compressor inlet along with the combustion products.
