Source of heat sounds like a fantastic forecast of the most daring futurologists. Geothermal power plants use the direct method of extracting heat from groundwater. It is quite simple water is pump through pipes laid in wells. Passing through these pipes under pressure, which, at the exit from the ground, falls on (STU) and rotates them. At the same time, STUs generate electrical energy, and the steam again turns into water, which goes underground for heating, and the cycle repeats. Geothermal power plants are built in Kamchatka, Iceland, Kenya, New Zealand wherever there is a relatively.
The water heats up and turns into steam
Accessible source of high temperature since water must Spain Phone Numbers List be turn into steam). And at the same time, steam is easily accessible – extremely expensive drilling of wells for many kilometers deep into the earth’s crust is not requir. For example, at the Pauzhetskaya GeoTPP (Kamchatsky Krai), wells with a depth of 366 m to 1205 m are us. Of course, hot steam at GeoTPP can serve as a source of heat for boiler houses, and be us for heating nearby towns and cities from GeoTPP, which makes heat supply very affordable and environmentally friendly. But not everywhere in Russia there are volcanoes and geysers.
Geothermal installations with heat pumps
Therefore the second type of geothermal USA CFO installations with low-potential heat of the earth is also us. Inde, at a depth of 8–10 m, the temperature never drops below +4–10 ºC (depending on the region). Accordingly, in winter it is -20 ºC outside, and +5 ºC underground. The heat pump extracts this heat from underground, concentrates it and transfers it to the building heating system as heat at a temperature of 45-75 ºC. are usually not us to generate electrical energy, more often they are us directly for heating buildings. The heat pump takes heat/energy from any sources of low-grade heat.
