Abstract
In a combined cycle system including a gas turbine (412), a steam turbine (420) and a heat recovery steam generator (436), wherein gas turbine exhaust is used in the heat recovery steam generator (436) for reheating steam for the steam turbine (420), an improvement wherein steam is extracted from the high pressure section (422) of the steam turbine 420), conducted to the gas turbine (412) for cooling hot gas turbine parts, and returned to the intermediate pressure section (424) of the steam turbine (420).
