HEAT-AND-POWER GENERATING AND INDUSTRIAL WASTE PROCESSING COMPLEX Russian patent published in 2001 - IPC

FIELD: high-temperature geothermal systems for heat and power generation and industrial waste processing. SUBSTANCE: complex using steam-water mixtures taken from geothermal wells has geothermal service well, heat-transfer apparatus, secondary coolant circuit, turbine-generator set, steam condenser, pump, and waste processing system. Novelty is that delivery and inspection wells are introduced, metering pump is used, service well outlet communicates with turbine-driven separator which is connected to generator; one of separator outputs is connected to input of heat- transfer apparatus whose secondary coolant is service water; heat-transfer apparatus has consumed-water outlet and thermal-water outlet; the latter communicates through first metering pump with delivery-well inlet; second output of separator is connected to gauze separator whose output is coupled with turbine-generator set; steam condenser is mounted in tandem with turbine-generator set; its output is connected to input of first metering pump. Waste processing system has liquid radioactive waste container connected through second metering pump to delivery-well inlet; inspection well accommodates delivery-well inspection instruments and control devices of metering pumps; distance between delivery and inspection wells meets condition R_d-s/R_r≥ 2,, where R_d-s is distance between delivery and service wells; R_r is radius of service-well effective range. EFFECT: enhanced available heat factor of geothermal well; enlarged range of wastes processed. 1 dwg
