GEOTHERMAL PLANT Russian patent published in 1995 - IPC

FIELD: heat-power engineering. SUBSTANCE: plant has geothermal well 1 and artesian well 11, high-pressure separator 2 and low-pressure separator 4, turbogenerator 3, condenser 5, heating water deaerator 7, heating water preheaters 6 and 8; plant is additionally provided with steam-jet ejector 9, its cooler 10 and condensate pump. Active medium inlet of ejector 9 is connected to steam outlet of low-pressure separator 4; passive medium inlet is connected to condensate gas discharge branch pipe and outlet is connected with atmosphere through cooler of ejector 10. Inlet of cooler of ejector 10 is connected, by the medium being heated, to discharge branch pipe of condensate pump and its outlet is connected to heating system supply line 12 through heating water preheaters 6 and 8. To increase flow rate of heating water, outlet of artesian well 11 is connected to suction branch pipe of condensate pump. It is good practice to connect inlet of medium being heated in way of flow of heating water to water outlet of cooler of ejector 10 and outlet shall be connected to inlet of deaerator 7 whose outlet is connected to inlet of second (in way of flow of heating water) preheater 8 which may be made as mixing unit. Second inlet of preheater 8 is connected to steam outlet 14 of high-pressure separator 2. EFFECT: enhanced reliability. 4 cl, 1 dwg
