GEOTHERMAL HIGH-PRESSURE FLUID-MEDIUM POWER PLANT AND ITS MODULE

摘要

FIELD: power engineering. SUBSTANCE: power plant using geothermal high-pressure fluid medium has primary separator for bifurcating the fluid medium so that one channel carries high-pressure steam and other channel, high- pressure liquid. Primary steam turbine in high-pressure steam channel uses high-pressure steam for power generation and for production of heat-depleted high-pressure steam. Secondary separator functions to separate heat-depleted high-pressure steam into steam component and liquid component. Primary heat exchanger is fed with high- pressure liquid and steam component to transfer heat of the latter thereby producing low-pressure steam and cool high-pressure liquid. At least one module of power plant incorporates low-pressure steam turbine operating on low-pressure steam to produce electricity and heat-depleted low-pressure steam; evaporating condenser holding organic liquid and functioning to receive heat-depleted low-pressure steam and to convert it into condensate, as well as to evaporate organic liquid; organic-steam turbine using evaporated organic liquid produced in evaporating condenser to generate electricity and to produce heat-depleted organic liquid; condenser that functions to condense heat-depleted organic steam and to convert it into liquid; liquid heater; pump used to convey hot liquid from heater back to evaporating condenser; pipeline conveying condensate from condenser to heater. EFFECT: improved design of geothermal power plant. 10 cl, 2 dwg
