ABSTRACT:
In a combined cycle system (10) which includes a gas turbine (12), a steam turbine (20); and at least one heat recovery steam generator (34) including evaporator(s) (38, 42, 46) operating at one or more pressures, and where condensate from the steam turbine (20) is evaporated by exhaust gas from the gas turbine (12) and returned to the steam turbine (20), the improvement comprising a closed loop cooling air circuit arranged such that hot cooling air from the gas turbine (12) is passed in heat exchange relationship with water from that one or more of the evaporators (46) in the heat recovery steam generator (34).
