FIELD: heating systems.
SUBSTANCE: invention refers to heat engineering, and namely to geothermal power plants producing electric energy based on using the heat of geothermal sources. In a geothermal power plant with circuit of heat carrier which includes gas separator, and waste heat exchangers of gas-turbine plant exit gas heat, which are connected with a well, and heat exchangers installed in condensate feed path of steam-turbine circuit, the organic fuel combustion products after gas turbine enter immediately the direct-contact heat exchanger installed on gas separator discharge thermal water piping. Thermal water mixture together with organic fuel combustion products moves through heat exchangers installed in condensate feed path of steam-turbine plant.
EFFECT: improving operating efficiency of geothermal power plant due to preventing formation of carbonate deposits in geothermal equipment, eliminating hazard of blockage of back pumping well, improving energy potential of thermal water passing through heat exchangers, and complete elimination of pollution of the environment with organic fuel combustion products.
