Abstract:
A combined cycle power plant and a method for operating a combined cycle power plant are presented. The combined cycle power plant includes a condensate recirculation pump to recirculate flow medium from downstream of a condensate preheater system to upstream of the condensate preheater system. An adequate flow temperature at the upstream of the condensate preheater system may be maintained to prevent acid gas dew point corrosion. The condensate recirculation pump may use a venturi effect to convert a high pressure of a condensate supplied by a condensate extraction pump to a suction pressure for the recirculation.
