Abstract: Combined cycle power plants are disclosed that utilize a stream of compressed flue gas and fuel that has been passed through a reformer (a thermochemical recuperator) to increase its thermal and chemical value and, along with the output of an air compressor, is fed into the gas turbine combustor. In preferred embodiments the thermochemical recuperation and flue gas recirculation are incorporated into combined cycle power plants that utilize either two gas turbines or reheat gas turbines.
