FIELD: electricity.
SUBSTANCE: invention relates to the field of power engineering, in particular to power plants using the energy of deep heat of the Earth. Petrothermal power plant comprises a well, drilled down to the depth with the bottomhole temperature no less than 600° C, the heat take-off system located in the well, containing the steam boiler, two connected pipelines, each of which consists of separate parts, and the parts of the water injection pipeline are connected with the parts of the steam removal conduit with rigid bars forming the sections, while a part of the well near the steam boiler with coverage of its heating zone, is filled with a water-proof material, the other part of the well is filled with rock lifted to the surface during well drilling with observance of its location in earth crust in the place of drilling. The mounting device of heat take-off system of petrothermal power plant includes a mounting derrick with the hydrolift, bench, made as a sliding welding table with chamfers forming at the centre of the table, when these parts are connected, an opening with the possibility of advancement through it into the well of sections of the heat take-off device.
EFFECT: reliable operation of petrothermal power plant, power increase is ensured.
