Thermal power generation is divided into pure power supply and power generation and heat supply according to the function of the thermal power generation. The power generation of a steam turbine, the power generation of a gas turbine and the power generation of a diesel engine are divided according to a prime motor. According to the fuel, the fuel mainly comprises coal power generation, fuel oil power generation and gas power generation. In order to improve the comprehensive economic benefit, the thermal power generation should be carried out as close to the fuel base as possible. In large cities and industrial areas, combined heat and power supply should be implemented, and a fuel oil system is an important auxiliary system of a boiler in a thermal power plant and mainly used for warming the boiler and igniting coal with relatively high ignition point in the starting, stopping and abnormal operation processes of the coal-fired boiler. And the unstable combustion of the boiler is caused when low load or poor-quality coal is used, the stable operation of the whole unit can be directly influenced, and the combustion of the boiler is stabilized by using fuel oil at the moment. At present, a common fuel oil system enters an oil storage tank through compressed air, and oil is filled into a small oil gun for oil injection. The instability of the oil storage tank causes potential safety hazards to an on-site fuel system, namely the oil storage tank of the fuel system needs to be supplemented with oil fuel in time according to the oil consumption, and when the liquid level of the oil storage tank is low, the fuel system is quickly closed and opened to supplement the oil to the oil storage tank; when the liquid level of the oil storage tank is high, the quick-closing valve is closed to stop oil supplement.
