Geothermal Power Plant

A geothermal power plant is basically a thermal power plant that uses steam power to move a turbine coupled to a generator with the big difference that the heat source comes naturally from the underground, in order to seize this power source wells are built where water is injected thus obtaining steam that is conducted from the different wells to the turbine.

Separator
It separates steam from geothermal water, after it has been extracted water is then returned to the surface to the reservoir for it to be heated again.

Steam turbine
The steam turbine at a geothermal power plant can receive water at a moderate temperature mixed with a low boiling fluid, it can also receive dry steam directly from underground through flash high pressure wells.

Condenser
Steam gotten from the boilers is conducted at high pressure to activate the turbine’s blades, thus moving the turbine’s rotor along with the generator’s rotor where electricity is produced.
At this stage power recovery is made in two extra steps, since steam with lower pressure recirculates to the medium and low pressure turbine to take max advantage of power generation.

Cooling tower
System’s cooling cycle water goes through the cooling tower which frees heat to the atmosphere and gets cold water to recirculate.
