What is fuel oil?

The so-called fuel oil in the refining industry refers to a type of oil specifically used as fuel for various types of industrial combustion equipment (including boilers, etc.). It does not include gasoline and light diesel oil. There are many types of fuel oil, some with low viscosity and some with very high viscosity, but for the most part, they are basically relatively viscous heavy fuels. The main raw material for producing this type of heavy fuel oil is the residual oil left after crude oil is distilled under normal pressure and vacuum.

In combustion equipment, fuel oil is injected into the furnace through nozzles under pressure. If the viscosity of the fuel oil is too small, the injection distance will be too close, which can easily cause local overheating; if the viscosity is too high, the injected fuel oil droplets will be too large, making it difficult to burn completely and easily generating black smoke.

Four major uses

1. Fuel oil consumption in the power industry is mainly used for ignition of fuel-fired power generation, heating units, and coal-fired units. , combustion-supporting and fuel-stabilizing oil.

2. The fuel oil consumed in the steel industry is mainly used for heating furnaces, self-provided power plants for power generation and heating, and refractory materials.

3. The fuel oil consumed by the building materials industry is mainly used for the production of flat glass and building sanitary ceramics. With the improvement of product quality requirements, the production of some high-end products will gradually turn to natural gas and liquefied petroleum gas as fuel. .

4. The use of fuel oil in the petrochemical industry is mainly for power generation in self-owned power plants, domestic heating in oil fields, heat for production processes in refineries, raw materials and fuels for fertilizer plant production, and other chemical production.
