Abstract

The present invention provides fuel oil which is applicable for middle and small boilers, the weight percentage component includes: heavy oil 55 to 80 percent, light oil 15 to 35 percent, additive 5 to 10 percent, the weight fraction of the additive includes: cation surface active agent contained fluorin 1 to 5 fractions, dicyclopentadienyl iron 1 to 3 fractions, zinc naphthenate 1 to 3 fractions, solutizer 1 to 5 fractions, glycol 10 to 15 fractions, viscosity modifier 2 to 15 fractions. The present invention is the fuel oil which is applicable for middle and small boilers, and is high in efficiency and energy saving, high in heat value, environmental friendly and safe in use, when application, the present invention is clean, the pollution is little, the transport and the storage are easy, when the fuel oil is put in the environment at -10 DEG C, the fluidity is still normal, and the oil saving volume can reach more than 15 percent, and the fuel oil is particularly applicable for middle and small boilers.

Description

technical field [0001] The invention relates to a fuel oil used for boilers, in particular to a fuel oil composition mainly composed of heavy oil. Background technique [0002] Heavy oil is an important fuel oil, which has the advantages of cheap price and high calorific value, and is favored by boiler users. [0003] However, the important viscosity is high and the flash point is low, which is not only inconvenient for storage, transportation and use, but also has a large amount of exhaust gas emission and serious environmental pollution, which limits its industrial application. Therefore, for a long time, it is generally used in large-scale industrial combustion equipment. [0004] In order to overcome the above-mentioned defects of heavy oil, many patents disclose respective technologies, such as Chinese patent application number: 01133373.1 discloses a kind of heavy oil composition containing N-hydroxypropylene diamine cationic emulsifier, the actual use results show th...
