Abstract
A combined cycle power plant includes a gas turbine, a steam turbine and a heat recovery steam generator. The heat recovery steam generator is arranged to receive exhaust gas from the gas turbine for reheating condensate from the steam turbine and generating steam for the steam turbine. And the heat recovery steam generator includes at least one drum evaporator configured to receive a first part of the condensate; a pump configured to receive a second part of the condensate and increase the second part of the condensate to an elevated pressure; and a high-pressure assembly configured to receive the condensate from the pump and operate the condensate from the pump at a subcritical up to a supercritical pressure range.
