Problems solved by technology

However, when polyoxymethylene is used as a boiler fuel, there are still the following problems: 1. Compared with hydrocarbon fuels, it has strong water absorption and is easily oxidized when exposed to air, resulting in strong corrosion to metals; 2. The value is low, the ignition temperature is high, and the combustion alone is not sufficient; 3. It is easy to polymerize after long-term storage
If these problems cannot be properly solved, long-term use of polyoxymethylene acetal will cause adverse effects on combustion appliances and fuel delivery systems

Abstract

The invention relates to high-cleanness liquid boiler fuel. The fuel is prepared by blending following raw materials by volume: 60-80% of polymethoxymethylal, 13-29.5% of heavy naphtha, 5-10% of fatty acid methyl ester and 0.5-2% of an additive. The additive includes, by mass, 10-20% of alkylphenol barium, 10-20% of 2,6-bis(1,1-dimethylethyl)-4-methylphenol, 50-75% of nitropropane, 2.5-5% of ethylene glycol monophenyl ether, 1.25-2.5% of trimethyl borate and 1.25-2.5% of N,N'-bis(salicylidene)-1,2-propanediamine. The calorific value of the fuel is substantially equivalent to the calorific value of Chinese national standard 0# diesel oil, consumption amounts of the fuel and the diesel oil are at the same level, but SO2 in combustion emission of the fuel is reduced by about 60% than that of the diesel oil, NOx in combustion emission of the fuel is reduced by 30% or above than that of the diesel oil, and particles in combustion emission of the fuel are reduced by about 50% or above than those of diesel oil, and therefore cleanness of the fuel is significantly improved.

Description

technical field [0001] The invention belongs to the technical field of alcohol ether fuel, and relates to a clean alcohol ether fuel whose calorific value is equivalent to that of burning diesel oil but whose pollutant emission is significantly lower than that of burning diesel oil. Background technique [0002] The world's energy reserves are becoming increasingly scarce and environmental problems are becoming more and more serious. Energy and environmental issues have attracted great attention from all countries in the world. Seeking new clean alternative energy has become a global issue. [0003] Environmental problems have become an important issue restricting the rapid development of my country's economy. my country's current boiler fuels commonly used include coal, natural gas and fuel oil. Among them, coal, as the main fuel, will produce a large amount of pollutant emissions, seriously affecting the atmospheric environment. Especially after the northern region enter...
