Deaerator heat exchanger for combined cycle power plant
This patent describes a combined cycle power plant. It comprises a steam turbine including an inlet portion for receiving motive steam and an exhaust portion for exhausting the motive steam that is spent by the steam turbine; a condenser connected to the exhaust portion of the steam turbine for receiving the spent motive steam and for condensing the spent motive steam to a supply of condensate; a gas turbine including an exhaust portion for exhausting waste heat that is produced by the gas turbine in the form of exhaust gases; a heat recovery steam generator connected between the exhaust portion of the gas turbine and the steam turbine, for receiving the waste heat exhausted by the gas turbine, for generating the motive steam from a supply of feedwater heated by the waste heat, and for supplying the motive steam to the steam turbine; a deaerator connected to the condenser for receiving the supply of condensate and for deaerating the condensate to provide the supply of feedwater to the heat recovery steam generator; and a heat exchanger.
