GEOTHERMAL POWER SUPPLY PLANT Russian patent published in 2023 - IPC F24T10/20 

FIELD: energy.

SUBSTANCE: autonomous power and heat supply installations using the geothermal energy of the Earth, used to supply electrical and thermal energy. A geothermal power supply installation for consumers contains a first pump located in a well, the output of which is connected by pipelines through a filter for purifying geothermal water from rock and salt impurities to an evaporator, which is connected to an economizer, the output of which is connected to the input of the second pump, which is connected to a pipeline through a fine filter, the end of which is intended for immersion into the injection well. The output of the second pump through the first valve is connected to the first input of the heat supply circuit heater, the first output of which is connected through the second valve to the input of the fine filter. The evaporator is connected by a pipeline to a turbine, the output of which is connected to an extraction heater, the outputs of which are connected by pipelines to an economizer and to an air-cooled condenser, the output of which is connected to a third pump, the output of which is connected to the second input of the extraction heater. The second outlet of the circuit heater is used to supply heated water to the consumer of thermal energy. The input of the fourth pump is intended to receive cooled water from the thermal energy consumer, and the output of the fourth pump is connected by a corresponding pipeline to the second input of the heat supply circuit heater.

EFFECT: increased reliability of the geothermal installation.
