ABSTRACT:
A combined cycle power system is disclosed in which condensate from a steam turbine is reheated in at least one heat recovery steam generator by exhaust gas from at least one gas turbine, and wherein at east one heat recovery steam generator includes at least one superheater and at least one reheater. In a preferred arrangement, the high temperature section of the superheater is located within the heat recovery steam generator so as to present first heat exchange surfaces to exhaust gas entering the heat recovery steam generator from at least one gas turbine, to thereby lower the exhaust gas temperature at the inlet to the reheater.
