Liquid combustion adjuvant for coal

Abstract

The present invention discloses combustion promoter, and is especially one kind of liquid coal combustion promoter. The liquid coal combustion promoter is constituted with loosening agent, catalyst, oxidant, sulfur fixing agent, reinforcer, etc; and is prepared through dissolving sodium chloride, potassium nitrate, potassium permanganate, calcium chloride, sodium carbonate and cerium nitrate in water. It is suitable for bituminous coal, lignite, old coal, etc. and can reach one 20-30 % raised heat effect, coal saving effect and pollution reducing effect.

Description

technical field [0001] The present invention relates to a combustion accelerant, more specifically, it relates to a liquid combustion accelerant for coal. Background technique [0002] Fuels used in the world today can generally be divided into liquid fuels (such as gasoline, diesel, etc.), gaseous fuels (such as natural gas, gas, etc.), solid fuels (such as coal, charcoal, etc.), nuclear fuels (such as nuclear fission etc. However, coal in solid fuel is still used as the main fuel in our country. Regardless of industry or civil use, coal, as one of the basic energy sources, plays an important role in the construction of the national economy. From the present point of view, the utilization of coal is very low, and how to improve the reasonable utilization of coal has become a crucial issue at present. When coal is burned, only when the temperature reaches 300-400°C, coal will decompose into a combustible substance, such as Hydrocarbons wait until they are burned. In order ...

From the present point of view, the utilization of coal is very low, and how to improve the reasonable utilization of coal has become a crucial issue at present. When coal is burned, only when the temperature reaches 300-400°C, coal will decompose into a combustible substance, such as Hydrocarbons wait until they are burned. In order to achieve full combustion of coal, people think of ways such as how to increase the temperature in the furnace and strengthen ventilation, etc., which are not ideal. The decomposed combustible volatiles in coal cannot be completely burned. It is decomposed into carbon black and other substances by heat and discharged into the atmosphere, which not only wastes energy, but also pollutes the environment

So far, no liquid coal combustion aid has been found to strengthen the combustion of coal, improve combustion quality and thermal efficiency, reduce smoke emission and reduce environmental pollution.
