The nature of fuel oil mainly depends on the nature of crude oil and the processing mode, and the main specifications that determine the quality of fuel oil include Viscosity, Sulfur Content, Pour Point and other fuel oil used for power plants, and the Content of Vanadium and Sodium is also specified.
Most petroleum products can be used as fuel, but fuel oil has different interpretations in different regions.
The European concept of fuel oil generally refers to the black viscous residue of crude oil after distillation, or its incorporation with lighter components, mainly used as the fuel for steam furnaces and various heating furnaces or as large slow diesel fuel and as a variety of industrial fuels.
However, in the United States it refers to any flammable liquid or liquefiable petroleum product with a flash point of not less than 37.8°C. It can be either Residual Fuel Oil (also known as Heavy Fuel Oil) or Heating Oil.
Distillate fuel oil can be obtained not only directly from distilled crude oil (i.e. straight run), but also from other processing processes such as cracking and then distillation.
Mechanical impurities
Mechanical impurities can clog the filter screen, causing oil pump wear and nozzle clogging, affecting normal combustion.
Mechanical impurity detection in general the GB/T 511-2010 "the oil and oil products and mechanical impurity additives act SH101C automatic mechanical impurity content meter Is according to the national standard GB/T511 "petroleum products and additive mechanical impurity measurement method (weight) of the requirements of the design, applicable to the determination of the various types of light oil products, heavy oil, lubricating oil and additives, the content of mechanical impurities.
