What are the different types of geothermal power plants?

There are three different types of geothermal power plants: dry steam plants, gleams of steam plants and binary cycle plants. Geothermal power plants use water that is naturally heated by Earth to create electricity. This is called geothermal water. Plants use this geothermal water to turn the turbine blades of the plant. Each type of power plant meets this power in a slightly different way.

When a geothermal power plant uses steam in the same form as the ground, the plant is called a dry steam plant. In dry steam geothermal power plants are drilled into the rock until it reaches the tank. A temperature reaching a steam of 302 ° F (150 ° C) or more is brought to the surface. Once the steam reaches the turbine, the turbine blade turns. This creates electricity. The pressure keeps the water in the liquids d, although the water temperature is significantly above the boiling point. As soon as the surface reaches, the pressure is released and the water greater than 360 ° F (182 ° C) flashes into steam. Steam is then used to turn the turbine bladesy. Water that does not turn to steam, as well as the water that condenses after turning to the steam, is pumped back into the tank.

binary geothermal power plants The binary cycle does not use water to turn the turbine blades. Rather, water with temperatures between 225-360 ° F (approximately 107.2-182.2 ° C) is used to heat a separate fluid, which has a boiling point significantly below the water point. When this liquid is evaporated, steam is used to turn the turbine blades. In this system, water and liquid are never combined. Because these plants can use fluids with boiling points lower than water, they can use geothermal water with a lower temperature.

In areas where there is hot, dry rock or where there is not enough water pressure, a system called thermal energy called Hot Dry Rock, called improved energy systems in North America, can be used. In this system, two holes are drilled into the rock. The water is then pumped into a rockover one hole. The heat of the rock warms water, which is then pumped into the second hole and is used to produce electricity. The water is then pumped back to the first hole to restart the cycle.
