Power generation refers to the production process of converting water energy, thermal energy of petrochemical fuels (coal, oil, natural gas), nuclear energy, solar energy, wind energy, geothermal energy, ocean energy, etc. into electrical energy by using a power generation power plant. It is used to supply the needs of various sectors of the national economy and people's lives. According to the type of energy source, the power generation power plant is divided into thermal power plant, hydroelectric power plant, nuclear power plant and other energy power generation power plant. Hydropower generation can only be realized in specific environments such as rivers and river basins. Nuclear power generation requires a large investment, so thermal power generation is more common. Thermal power generation devices in the prior art generally include a steam generator and a turbogenerator. The turbogenerator is connected to the power distribution cabinet through wires. Power generation, the waste steam after doing work is sent back to the boiler for recycling through the condenser, circulating water pump, condensate water pump, feed water heating device, etc.

The power generation device with this structure has a complex structure and high cost, because the boiling point of water is 100°C, there is still a large amount of waste heat after power generation, and the utilization rate of heat energy is low. The waste steam needs condensers, circulating water pumps, condensate water pumps, and feed water heating devices, etc. A large number of complex equipment can be recycled, and the fuel used is non-renewable energy, and it will cause a lot of pollution to the environment when burned.
