The given diagram illustrates the process of producing electricity from using the heat from geothermal zones.
Overall, it is apparent that the process contains five main stages, starting with pumping cold water into the underground and ending with generating electricity by a generator. Another key feature is that this process is completely environmentally friendly and suitable to replace fossil fuels in the long run.
In the beginning of the process, cold water will be pumped into the injection well, which is located deep underground, and goes through a geothermal zone with high-temperature rocks. In this area, the water will be heated significantly by hot rocks before going out from a production well and being pumped up back into a condenser.
In the condenser, hot water will then release a considerable amount of steam, which will be navigated into a chamber with a huge turbine. In the following stage, the steam will push the turbine to spin in a circle and generate power, which will be then turned into electricity by the generator before being transmitted to nearby high-voltage power poles.
