Thermal power generation is divided into pure power supply and both power generation and heating based on its function. According to the prime mover, it is divided into steam turbine power generation, gas turbine power generation, and diesel engine power generation. According to the fuel used, there are mainly coal-fired power generation, oil fired power generation, and gas fired power generation. To improve comprehensive economic benefits, thermal power generation should be carried out as close as possible to the fuel base. In large cities and industrial areas, cogeneration should be implemented.
