A power plant is a power plant that converts some form of primary energy (e.g., water, steam, diesel, gas) into electrical energy for use in stationary facilities or transportation. Thermal power generation is power generation using thermal energy obtained by burning fuel (coal, petroleum and products thereof, natural gas, and the like). There are two main forms of thermal power generation: the high-temperature and high-pressure steam generated by the boiler is used for driving a steam turbine to rotate to drive a generator to generate electricity, and the generator is called a steam turbine generator unit; the fuel enters the gas turbine to directly convert the heat energy into mechanical energy to drive the generator to generate electricity, and the generator is called a gas turbine generator set.
