Abstract

An environment protection type efficient additive for fire coal contains proportionally potassium chloride, potassium hypermanganate, calcium lime, potassium nitrate and sodium nitrate. It has high effect to increase heat efficiency, decrease the content of C in sinder and the exhaust of toxic harmful gases, and elongate combustion time.

Description

technical field [0001] In particular, the present invention relates to a coal combustion additive. Background technique [0002] Coal is one of the most common and main energy sources, and it is widely used in industrial and mining enterprises and daily life. However, coal also has the obvious disadvantages of low combustion efficiency and environmental pollution. Therefore, improving the combustion efficiency of coal combustion, so as to achieve the purpose of saving coal and reducing the pollution of coal combustion to the environment, has become an important topic of energy conservation at present. At present, the method of adding coal-burning additives to coal-burning is mainly adopted to achieve the purpose of saving coal. By adding coal-burning additives, the coal-fired combustion can be made more fully. However, the existing coal-fired additives have no obvious energy-saving effect, still cause serious environmental pollution, and have high costs. Contents of the...
