An indirect gas turbine power plant is provided which includes primary and secondary combustors wherein fuel is burned and heat is conveyed to a turbine working medium which is subsequently passed through the turbine section of a gas turbine. The gas turbine includes both a compressor section and a turbine section. The primary combustor has a first inlet for receiving exhaust air from the turbine section, a second inlet for receiving fuel and an outlet for the discharge of products of combustion. The secondary combustor includes a first inlet for receiving at least a portion of the products of combustion from the primary combustor, a second inlet for receiving a portion of the products of combustion of the secondary combustor, and an outlet for the discharge of the products of combustion of the secondary combustor. An air heat exchanger for conveying heat from the products of combustion to the compressed air is positioned within the secondary combustor. This heat exchanger includes an inlet for receiving compressed air from the compressor section of the gas turbine, and an outlet to direct the compressed, hot air out of the secondary combustor for passage to the turbine section.
