The properties of fuel oil mainly depend on the properties and processing methods of crude oil. The main specifications that determine the quality of fuel oil include viscosity, sulfur content, freezing point and other fuel oils for power plants, and the contents of vanadium and sodium are also stipulated.
Fuel oil is widely used in power plants, marine boilers, heating furnaces, metallurgical furnaces and other industrial furnaces.
Fuel oil is mainly composed of petroleum pyrolysis residue and straight-run residue, which is characterized by high viscosity and contains many non-hydrocarbon compounds, resins and asphaltenes.
