Geothermal energy is natural heat energy extracted from the earth crust, the energy comes from lava in the earth, exists in a thermal form, is energy causing volcanic eruption and earthquake, and geothermal power generation is the most important mode of geothermal utilization. The high temperature geothermal fluid should be applied first for power generation. The principle of geothermal power generation and thermal power generation is the same, and the heat energy of steam is converted into mechanical energy in a steam turbine, and then the mechanical energy drives a generator to generate power. The difference is that geothermal power generation does not need to be provided with a huge boiler like thermal power generation, does not need to consume fuel, and uses geothermal energy as energy. The process of geothermal power generation is the process of converting underground heat energy into mechanical energy first and then converting the mechanical energy into electric energy. To utilize the underground heat energy, a "heat carrier" is needed to bring the underground heat energy to the ground. The heat carriers that can be utilized by geothermal power plants are mainly natural steam and hot water in the ground. The geothermal power generation method can be divided into two main types, namely steam type geothermal power generation and hot water type geothermal power generation, according to the difference of the type, temperature, pressure and other characteristics of a heat carrier.
