FIELD: power engineering; alternative power supplies. SUBSTANCE: power plant has gas separator communicating with geothermal water well and connected through gas outlet line to combustion chamber and through waste outlet line, to steam generator whose outlet is connected to steam turbine; turbine condenser outlet is connected to geothermal water pumping well; plant is provided, in addition, with has-turbine unit as well with recovery and regenerative heat exchangers and with turbine steam extraction line; combustion chamber is installed in line inter connecting compressor and turbine of gas-turbine unit; exhaust pipe of the latter is connected via exit gas dump lines to recovery heat exchangers and to steam generator; recovery heat exchanger first along gas path is installed in line through which water is discharged from gas separator to steam generator and second one, in line for geothermal water delivery from well to gas separator; regenerative heat exchanger is mounted on side of medium being heated in line for water discharge from gas separator downstream of recovery heat exchanger and on side of heating medium its inlet is connected to steam extraction line outlet, to gas separator. EFFECT: improved design. 1 dwg
