Geothermal Energy Dry Steam Power Plant

Dry steam plants are the most common types of geothermal power plants accounting for about half of the installed geothermal plants.

Geothermal energy dry steam power plant.

All geothermal power plants use steam to turn large turbines which run electrical generators. Flash steam plants take high pressure hot water from deep inside the earth and convert it to steam to drive generator turbines. This steam travels from the production well to the surface and through a turbine and after transferring its energy to the turbine it condenses and is injected back into the earth. In the geysers geothermal area dry steam from below ground is used directly in the steam turbines.

In other areas of the state super hot water is flashed into steam within the power plant and that steam turns the turbine. In flash steam power plants pressurized high temperature water is drawn from beneath the surface into containers at the surface called flash tanks where the sudden decrease in pressure causes the liquid water to flash or. They work by piping hot steam from underground reservoirs directly into turbines from geothermal reservoirs which power the generators to provide electricity. At peak production these dry steam geothermal power plants are the world s largest single source of geothermal power producing up to 2 000 megawatts of electricity an hour.

Other power plants built around the flash steam and binary cycle designs use a mixture of steam and heated water wet steam extracted from the ground to. These types are the oldest types of geothermal power plants the first one was built back in 1904 in italy. In such dry steam operations the heated water vapour is funneled directly into a turbine that drives an electrical generator. Dry steam plants use steam directly from a geothermal reservoir to turn generator turbines.

These plants use dry steam that is naturally produced in the ground. The first geothermal power plant was built in 1904 in tuscany italy where natural steam erupted from the earth. About 6 percent of the energy used in northern california is produced at 28 dry steam reservoir plants found at the geysers dry steam fields in northern california. After powering the turbines the steam condenses into.
