DEVICE FOR AND METHOD FOR GENERATION OF ELECTRIC POWER FROM GEOTHERMAL LIQUID RESOURCES Russian patent published in 1998 - IPC

FIELD: geothermal power production. SUBSTANCE: method involves generation of electric power in high pressure geothermal environment by means of its separation into high-pressure vapor and high pressure brine, extension of high pressure vapor in high-pressure turbine generator in order to generate electric power and cooled vapor, and by separation of liquid from cooled vapor in order to produce dried cooled vapor which pressure and temperature is less than those of high pressure vapor. Separated liquid and high-pressure brine are mixed in vaporizing chamber which generate vapor which mixes with dried cooled vapor and extended in low-pressure turbine generator in order to generate additional power. In addition some high pressure vapor is used for intermediate heating of dried cooled vapor and vapor which is generated in vaporizing chamber before extension of this vapor in low-pressure turbine generator. EFFECT: increased efficiency and service life. 10 cl, 4 dwg
