Abstract
A combined cycle power plant having a steam turbine, a gas turbine, a heat recovery steam generator, a deaerator and a condenser includes a heat exchanger for controllably exchanging heat between relatively cool condensate from the condenser and relatively warm feedwater from the deaerator in order to recover additional heat from the heat recovery steam generator and, thereby, improve overall efficiency of the combined cycle power plant.
