Abstract
A power generation plant comprising a gas turbine and a waste heat recovery boiler in which feed water is heat-exchanged with exhaust gas from the gas turbine to produce vapor. A steam turbine system incorporates a reheat turbine and a high pressure turbine to which the vapor is supplied from the waste heat recovery boiler, with a generator being driven by the steam turbine system and condenser for condensing vapor from the stream turbine system into condensate and for supplying the condensate to the waste heat recovery boiler as the feed water. The waste heat recovery boiler is provided with a secondary reheater, a super heater, a primary reheater reheating vapor to be supplied to the secondary reheater and an evaporator for evaporating the feed water from the condenser into vapor and for supplying the vapor to the super heater, in order with respect to the exhaust gas flow. The vapor produced in the super heater is introduced into the high pressure turbine and the vapor produced in the secondary reheater is introduced into the reheat turbine.
