A. Whether is commodity quantity formed when the basis leaves factory, fuel oil can be divided for commodity fuel oil and oil of fuel of for private use. Commodity fuel oil points to in leave factory the fuel that link forms commodity is oily; The raw material that oil of fuel of for private use points to to with Yu Lian the factory is produced or fuel and not was in leave factory the fuel that link forms commodity is oily.
B. The basis machines technological process, fuel oil can be divided to often press heavy oil, decompression heavy oil, catalysis heavy oil is mixed mixture heavy oil. Constant ballast oil shows refine factory often presses the heavy oil that device fractional distillation comes out; Decompression heavy oil points to the heavy oil that fractional distillation of device of refine factory decompression comes out; The heavy oil that catalytic heavy oil points to to fractional distillation of device of refine factory catalysis, cracking comes out (common weighs oily oar) ; Mixture heavy oil points to those who decrease ballast oil and catalytic heavy oil to mix commonly.
C. According to utility, fuel oil can be divided for marine fuel oil and furnace use fuel oil (heavy oil) etc fuel is oily.
3. Main use
Fuel oil is used extensively at furnace of shipping boiler fuel, heating furnace fuel, metallurgy and fuel of other industry furnace.
4. Oily standard of our country active fuel
Chinese petro-chemical head office consulted 1996 the most extensive fuel oily level is used on international; Association of American material trial (ASTM) oily standard of standard ASTMD396-92 fuel, made the occupation standard SH/T0356-1996 of our country.
1 mixes 2 is oil of fuel of cent of heat up in a steamer, apply to family expenses or small-sized burner uses industry. 4 mix gently 4 fuel oil is heavy qualitative heat up in a steamer distribute fuel oil or be the fuel oil that oil of fuel of cent of heat up in a steamer and residual fuel oil mix and becomes. 5 light, 5 heavy, 6 mix 7 is the residual fuel oil that viscosity and limits of Cheng of heat up in a steamer increase by degrees, mix to assemble and unassemble normal pulverization, need warm-up commonly when temperature is low.
Our country is used most is 5 light, date and 5 heavy, 6 7 fuel oil.
In new standard 5 - by 100 ℃ athletic viscosity comes to control of 7 fuel oily viscosity and to deal date to differentiate, the fuel oil that abroad imports is main it is to press classification of viscosity of motion of 50 ℃ , they are viscosity of motion of 50 ℃≥180mm/s and viscosity of motion of 50 ℃≥380mm/s two kinds big.
5. Homebred fuel oil is phyletic
Business uses oil of fuel of oil of 7 200 heavy oil, heavy oil, fuel, industry
6. Entrance fuel oil is phyletic
Oil of answer refine emulsification, abstruse in fuel of 180 oil of fuel of 380 oil of emulsification oil, fuel of 180 low sulfur, low sulfur, tall sulfur is oily
