Dust-proof and combustion-supporting additive of fired coal

Abstract

A dustproof and combustion-supporting additive of coal fired consists of alcohol, ethyl ether, burnt lime, Tween, nitrate and water proportionally. The process is carried out by mixing nitrate solution with lime milk and Tween to become emulsion, adding into alcohol, blending, adding into ethyl ether, and blending to obtain the final product. It can improve full burning rate of coal by 10-15%, hearth temperature 40-50 Deg C. and save coal 22.2-32.1%. It achieves less solid smoke displacement, simple raw materials and process.

Description

(1) Technical field [0001] The invention relates to a combustion-supporting and dust-removing additive for burning coal. (2) Background technology [0002] The existing coal-fired technology, whether it is industrial or civil, has disadvantages such as incomplete combustion, low combustion efficiency, high coal consumption, large emissions of smoke, dust, waste gas, etc., and serious environmental pollution. In order to reduce smoke and dust pollution, industrial coal-fired boilers have adopted technologies and equipment such as water film dedusting, and achieved better dedusting effects. But it has not fundamentally reduced the generation of smoke and dust by improving the combustion efficiency, so as to achieve the purpose of dust prevention and reduction of smoke pollution. In order to reduce impurities such as sulfur in coal to produce SO through combustion 2 and other harmful gases to the environment, the existing technology is only producing SO 2 After waiting for e...
