Abstract

The invention discloses composition for inhibiting alcohol-based fuel for boilers from producing nitrogen oxides. The composition comprises components in percentage by mass as follows: 9.6-25.6% of (4-ethoxyphenyl)phenylmethanone, 11.8-30.3% of 2-hydroxy-3-methyl ethyl valerate, 12.9-28.1% of 1-eth-1-ynyl-4-(pentyloxy)benzene, 14.8-33.5% of 2-(4-methoxy-1,4-cyclohexadiene-1-yl)-2-propyl alcohol, 11.9-27.8% of 3-methyl-1-indanone and 10.4-21.6% of 1-iso-propenyl-4-metoxybenzene. Thecomposition is added to the alcohol-based fuel in a ratio of 0.1-0.7wt%, the nitrogen oxides produced during combustion of thealcohol-based fuel can be obviously reduced, and emission of the nitrogen oxides in combustion flue gas of the boilers is averagely reduced by 36.4%.

Description

technical field [0001] The invention belongs to the technical field of alcohol-based fuel replacing boiler fuel, and relates to an additive for alcohol-based fuel, in particular to an additive composition capable of suppressing the formation of nitrogen oxides of alcohol-based fuel. Background technique [0002] Energy utilization is the main cause of air pollution. In my country's energy utilization structure, coal with serious pollution accounts for about 70% of the total energy consumption. Various fuels are burned in boilers and other combustion devices, producing a large amount of soot, sulfur oxides, nitrogen oxides, carbon monoxide, hydrocarbons and other pollutants. Thermal power generation, metallurgy, chemical industry, building materials, hospitals, schools and other enterprises and institutions and urban residents are equipped with industrial boilers or domestic heating boilers, especially small boilers, which are large in number, widely distributed, and have poo...
