ABSTRACT:
A geothermal steam turbine plant comprises a steam turbine operatively connected to a production well, an indirect-contact type main condenser into which a geothermal steam including non-condensed gas is introduced from the steam turbine, and a cooling water supply system for supplying cooling water to the main condenser. The non-condensed gas contained in the geothermal steam is ejected by a gas ejecting system comprising a geothermal steam jet ejector connected to the main condenser, a direct-contact type condensing system connected to the steam jet ejector for condensing the geothermal steam into the geothermal water including substantially no non-condensed gas by directly contacting the steam to the condensate from the main condenser, a pipe line for returning the condensed water from the condensing system to the main condenser, and a condensate water pipe line for circulating the condensate water pooled in the main condenser to the condensing system so as to be independently located from the cooling water system. The condensate water pipe line is branched from a condensate water pump assembled in a pipe line extending outwardly from the bottom of the main condenser.
