What is fuel oil
Fuel oil is a kind of refined oil, which is a heavy residual oil product other than steam, coal and diesel oil separated from petroleum refining, mainly used as fuel for Marine boilers and heating furnaces.
Second, the use of fuel oil
Fuel oil is mainly made of cracked residual oil and straight-run residual oil, which is characterized by large viscosity, containing non-hydrocarbon compounds, gum, asphaltene, and its main uses are as follows:
1, the power industry fuel oil consumption is mainly used for fuel power generation, heating units, coal-fired units ignition, combustion and stable fuel oil.
2, the fuel oil consumed by the steel industry is mainly used in heating furnaces, self-provided power plants, 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, some high-grade product production will gradually turn to natural gas and liquefied petroleum gas as fuel.
4, the use of fuel oil in the petrochemical industry is mainly in the power generation of self-provided power plants, domestic heating in oil fields, heat for refinery production processes, raw materials and fuels for fertilizer plant production and other chemical production.
3. Which oils are included in fuel oil
Fuel oil is a kind of refined oil, mainly including gasoline, kerosene, residual oil, coal tar and diesel oil, as the last product in the refining process, there are many types of fuel oil, according to different standards, fuel oil can be classified as follows:
1, according to the formation of goods at the factory, fuel oil can be divided into commercial fuel oil and self-use fuel oil. Commercial fuel oil refers to the fuel oil that forms commodities in the process of leaving the factory; Self-use fuel oil refers to the fuel oil that is used as raw material or fuel for refinery production and is not formed into a commodity at the factory.
2, according to the processing process, fuel oil can be divided into normal pressure heavy oil, vacuum heavy oil, catalytic heavy oil and mixed heavy oil. Atmospheric heavy oil refers to the heavy oil fractionated from catalytic and cracking units of refineries (commonly known as oil slurry). Mixed heavy oil generally refers to the mixture of vacuum heavy oil and catalytic heavy oil, including the mixture of residual oil, catalytic oil slurry and part of the asphalt.
3, according to the use, fuel oil is divided into two categories of Marine internal combustion engine fuel oil and furnace fuel oil, both categories include distillate oil and residual oil. Distillate is generally a mixture of straight-run heavy oil and a certain proportion of diesel, used in medium or high speed Marine diesel engines and small boilers. The latter is mainly vacuum residual oil, or cracked residual oil or a mixture of the two, or heavy petroleum fuel oil made of an appropriate amount of cracked light oil, for low-speed diesel engines, some medium-speed diesel engines, various industrial furnaces or boilers as fuel.
4. Is the fuel a dangerous chemical
Hazardous chemicals refer to highly toxic chemicals and other chemicals that have the properties of poisoning, corrosion, explosion, combustion, combustion, etc., and are harmful to human body, facilities and the environment. Fuel oil is a dangerous chemical, and most local safety bureaus require fuel oil production and operation enterprises to obtain a license before they can operate.
