PROBLEM TO BE SOLVED: To increase a pressure ratio and a specific output to a limit, and improve thermal efficiency of a gas turbine cycle sharply by serving a gas turbine combustor also as a heat exchanger, and using a fuel heating value in the other use. SOLUTION: A water feed pipe 1 is arranged in a combustor for generating combustion gas for driving a gas turbine as a combustor heat exchanger 4a, water 3 prescribed by a feed water pump 2 is supplied, and a supercritical steam 5 which is generated therein is supplied to a high pressure steam turbine through a steam regulating valve 7. After steam 5 which completes work is re-heated by a combustor heat exchanger 4b, its steam 5 is supplied to an intermediate pressure steam turbine, and supplied to a low pressure steam turbine after the steam 5 is re-heated by a combustor heat exchanger 4c so as to operate a power generator by power of a steam turbine. Steam which completes work is cooled with sea water and the like by a condenser, its obtained condensation 8 is circulated into the combustor heat exchanger 4a through an exhaust heat recovery heat exchanger 11, a feed water pump 2 by a condensate pump 2. |
