2燃料油(国外英文资料) Fuel oil One, breed characteristic The fuel oil is also called heavy oil and residuum, which is a kind of black and brown sticky liquid, which is moderate in viscosity, good in fuel and high in heat. Used for boiler fuel, the atomization is good, the fuel is completely, the carbon and ash are small, the corrosion is small. Flash point is higher, storage and use are safer. Fuel oil is a type of refined oil refined from crude oil, widely used in the fuel of boilers, heating furnaces, metallurgical furnaces and other industrial furnaces. The fuel oil is mainly made from the oil of petroleum and the oil of straight distillate, which is characterized by a large viscosity, containing non-hydrocarbon compounds, colloids and asphalts. The main technical indexes of fuel oil are viscosity, sulfur content, flash point, water, ash and mechanical impurities. Viscosity: viscosity is the most important performance indicator of fuel oil and is the main basis for the classification of fuel oil. It is a measure of the capacity of the fluid impedance, its size indicates the ease of the fuel oil, the ease of pump delivery and the ability to atomize. At present domestic commonly used is 40 ℃ kinematic viscosity (distillate fuel oil type) and 100 ℃ kinematic viscosity (residue fuel oil). Our country in the past of the fuel oil industry standards by engler viscosity (80 ℃, 100 ℃) as indicators of quality control, with 80 ℃ viscosity to differentiate the brand. The viscosity of oil is the ratio of the viscosity and density of oil. The unit of motion viscosity is Stokes, or Stokes. When the dynamic viscosity of a fluid is 1, the dynamic viscosity of 1g/cm3 is 1 stokes. The CST is the abbreviation of Centistockes, which means centis, one percent of one stokes. Sulfur content. High levels of sulphur in fuel oil can cause corrosion and environmental pollution. Depending on the amount of sulfur, the fuel oil can be classified as high sulphur and low sulphur fuel oil. Flash.
