ABSTRACT:
A dual cycle engine which includes both a steam turbine and a gas turbine. The engine includes an air compressor and a combustion chamber connected to the air compressor for burning fuel with air from the air compressor to generate a first gaseous output which drives a gas turbine. The engine also includes a heat recovery system for recovering heat from the gaseous output of the gas turbine after the gaseous output has passed through the gas turbine. The heat recovery system includes a heat exchanger for extracting heat from the gaseous output and for heating an input water stream to generate steam. The steam is heated further in a superheater that burns fuel and air at the same pressure as the combustion chamber to generate a second gaseous output that is combined with the output of the combustion chamber prior to the output from the combustion chamber being passed through the gas turbine. The steam from the superheater is expanded in a steam turbine to generate work therefrom. In the preferred embodiment of the present invention, the heat exchanger is a supercritical heat exchanger. The water input stream is preferably generated by condensing water from the gaseous output after the gaseous output has passed through the heat exchanger. The superheater may be constructed by utilizing a heat exchanger in the combustion chamber. In embodiments of the present invention that utilize a steam injected gas turbine, the steam injection is provided by the output of the steam turbine.
