Abstract

The invention relates to a clean fuel, in particular to a coal-based composite domestic fuel so as to solve the problem that existing domestic fuel oil has a lot of disadvantages. The composite domestic fuel is composed of light coal tar, methanol, a dispersing agent, a corrosion inhibitor, and a combustion-supporting agent. The light coal tar is the distillate distillated from coal tar during fractional distillation under a temperature below 280DEG C, and has a density of 0.91-0.99g / ml. The dispersing agent is any of polyisobutylene succinimide, phosphoric acid amide, alicyclic amine, and succinimide or a mixture of several of them in any proportion. The corrosion inhibitor is any of oleic acid glycol ester, N, N-bis(salicylidene)-propanediamine, benzotriazole, 2, 6-di-tert-butyl-p-cresol or a mixture of several of them in any proportion. The combustion-supporting agent is any of calcium naphthenate, magnesium naphthenate, iron naphthenate, and ferrocene or a mixture of several of them in any proportion. Being easy to ignite, the composite domestic fuel provided in the invention has good atomizing performance, more sufficient combustion, as well as higher thermal efficiency, the smoke blackness and other emission indexes all meet the requirements, and the economic effects are more significant.

Description

technical field [0001] The invention relates to a clean fuel, in particular to a coal-based composite civil fuel. Background technique [0002] In China, which has a population of more than one billion, civilian cooking fuel has always been an important issue for the national economy and the people's livelihood. At present, the expenses of Chinese urban and rural residents on cooking and heating fuel are basically the same as that of food expenditure. In recent years, due to the serious pollution of the urban environment, the use of coal stoves is prohibited, and the supply of LPG is not guaranteed and the price is expensive, so a number of diesel stoves using liquid fuels have appeared. However, fuel diesel also has the problems of shortage of supply, high price and serious pollution. Coal tar, methanol and other cheap raw materials produced on a large scale with coal as raw materials can replace diesel and LPG, opening up a new way for civil fuels. [0003] Coal tar ...
