  • Patent number: 8943836
    Abstract: Disclosed herein are embodiments of combined cycle power plants having elevated exhaust pressure from a steam turbine. The elevated exhaust pressure from the steam turbine may result in an elevated condensate pressure and temperature. A cooling system removes sensible heat from the condensate. The elevated condensate temperature results in a greater temperature difference between the condensate and the working medium in the cooling system. The amount of heat that is dissipated by the cooling system is proportionate to the heat transfer surface and the temperature difference between the condensate and the working medium. As a result of the greater temperature difference, a smaller cooling system configured to operate with a higher temperature condensate may be utilized in place of a larger cooling system configured to operate with lower temperature condensate. By reducing the size of the cooling system, the overall size of the combined cycle power plant may be reduced.
