Abstract

A heat recovery steam generator (200) uses heat energy extracted from the exhaust gas of a gas turbine to produce steam. The steam is provided to steam turbines of a combined cycle power plant. Intermediate pressure steam generated by an intermediate pressure evaporator (214) is routed to first and second intermediate pressure superheaters (220,236). Also, steam exhausted from a high pressure steam turbine (30) of a combined cycle power plant is reheated by first and second reheaters (228,236) within the heat recovery steam generator (200). The steam output by the intermediate pressure superheaters (220,236) is provided to an interstage admission port of an intermediate pressure steam turbine (40), and steam output by the first and second reheaters (228,236) is provided as the main input steam for the intermediate pressure steam turbine (40) of the combined cycle power plant.
