you are: Value of researches of a thermal stream

Steam geothermal deposits are the most valuable geothermal resources. They give dry, or peregretyj, steam plus small amounts of other gases, such, as carbon dioxide (carbonic gas), hydrogen sulphide and ammonia. The majority of researchers believe, that water or settles down basically along the edges and at the bottom of the tank, or co-exists together with steam on all tank in the form of the drops filling a time of rocks. In these systems in large cracks and a time steam prevails, and it supervises pressure and temperature in the tank [And]. A typical interval of temperatures - from 220 to 240 °s, and the maximum pressure - 3,4 MPa. It is possible to assume, that the tank replenishes with steam from boiling somewhere in system boiling or liquid water being somewhere in system as at drilling and operation of a chink pressure decreases. In the course of extraction it is warm often there is a small overheat of steam.

Steam geothermal konvektivnye systems are used for manufacture of electric energy in following areas: the Geyser (California, the USA) - 500 MVt, Larderello (Italy) - 380 MVt, Matsukava (Japan) - 22 MVt, Monte-Amiata (Italy) - 22 MVt, Vales-Kaldera (New Mexico, the USA).
