FIELD: heat-and-power engineering.
SUBSTANCE: invention is intended for producing of high-pressure superheated water and can be used in heat engineering, including in field conditions at oil deposits. Device includes steam generator, degasser for preparation of feed water, feed water injection pumps and deaerator for water conditioning, taken from natural source, and mixer, wherein for water supply into mixer downstream of deaerator pressure pumps are used. Injection pumps have common power drive in form of steam turbine, which working medium is steam, generated by steam generator. Cooled at turbine outlet steam is used for water heating in degasser and deaerator. Water-steam mixer is similar to liquid-propellant engine combustion chamber and has double-loop multi-nozzle head, wherein steam and water are separately supplied into mixer working cavity via own loop centrifugal nozzles.
EFFECT: steam-water mixer has discharge branch pipe to supply high-pressure superheated water to consumers.
