Abstract
A dual-fluid heat engine having a gas turbine and an open cycle steam turbine. The gas turbine has a compressor for compressing a first working fluid, the compressor having a compressor outlet. The gas turbine has a combustion chamber in fluid communication with the compressor outlet. The turbine portion of the gas turbine has an inlet in fluid communication with the combustion chamber for performing work by expansion of the first working fluid, and a gas turbine exhaust. A heat recovery exchanger is coupled to the gas turbine exhaust having a heat recovery inlet and an outlet for heating a second working fluid, water. The water is converted into steam in the heat recovery exchanger. A pump increases the pressure of the water prior to entrance in the heat recovery exchanger. An atmospheric exhaust expansion steam turbine extracts energy from the heated second working fluid to drive an electrical generator. An exhaust chimney takes the gas turbine exhaust and the steam turbine exhaust and rejects it into the atmosphere.
