METHOD TO BUILD UNDERGROUND EVAPORATION SYSTEMS IN HIGH-TEMPERATURE LAYERS OF TERRESTRIAL ROCKS FOR THERMAL POWER PLANTS Russian patent published in 2015 - IPC E21B7/14 E21C37/16 F03G4/00 

FIELD: construction.

SUBSTANCE: invention relates to construction of hydrothermal power plants, using thermal energy in deep layers of earth interior. The method to build underground evaporation systems in high-temperature layers of terrestrial rock includes the following: development of a system of evaporation cavities in an end section of a deep well by method of rock melting with a melting plant, and also use of an evaporation plant installed in the area of evaporation cavities instead of the melting plant, supplying fresh or sea water into evaporation cavities, where water sprayed onto hot surfaces of cavities turns into superheated high pressure steam and temperature, arriving to a turbogenerator producing power, and after steam condensation used to heat building with desalinated hot water. Concentrated residue of sea water after its evaporation may serve as raw material for chemical industry in order to extract precious rare chemical elements from them.

EFFECT: provides for waste-free and harmless production of cheap power, production of fresh water from sea water with the possibility of full automation of technological processes.
