Method for producing smoke-prevention, dust-contorl and energy saving combustion improver

Abstract

The production process of smoke-eliminating, dust removing and energy saving combustion improver includes a) crushing, grinding and mixing potassium chloride, magnesium chloride and Fe2O3, setting the mixture inside a reactor and mixing with water for reaction; b) crushing ammonium nitrite and setting inside one other reactor and mixing with water for reaction the product of the fore step; c) mixing crushed coarse whiting, nitric acid and water to produce calcium nitrate; mixing calcium nitrate with the product of step b) for reaction, stoving, adding RE, quartz, barite and carbonate for reaction, and adding kaolin to reaction to obtain the combustion improver. The combustion improver is used in coal combustion to perform the functions of catalysis, releasing heat, fixing sulfur and lowering environmental pollution.

Description

Technical field: [0001] The invention belongs to the field of chemistry, and particularly relates to fuels in the coal industry, in particular to a method for manufacturing a smoke-eliminating, dust-removing and energy-saving combustion-supporting agent. Background technique: [0002] my country is a big coal-consuming country. There are about 400,000 boilers, which consume 300 million tons of coal every year, more than 110,000 industrial kilns, more than 200 million tons of coal per year, and more than 200 million tons of civil coal. Due to the outdated equipment and technology , the boiler efficiency is low, the energy consumption is large, the exhaust gas emission exceeds the standard, and the atmospheric environment pollution is serious. Coal uses fuel oil or gas, but it requires huge investment, and also requires high operating costs after transformation. Potassium manganate, sodium salt, iron oxide and manganese dioxide.

Problems solved by technology

[0003] The technical problem to be solved by the present invention is: in the prior art, in order to improve the combustion efficiency of coal-burning, a combustion-supporting agent is usually used, and the described combustion-supporting agent comprises potassium permanganate, sodium salt, iron oxide, manganese dioxide, but high Potassium manganate is a strong oxidizing agent, which has low safety and high cost, and contains a large amount of sodium salts. The combustion-supporting agent of iron oxide and manganese dioxide is easy to coke, the combustion-supporting effect is not good, and it will cause secondary pollution. The present invention is The technical solution adopted to solve the above-mentioned technical problems in the prior art is to provide a method for manufacturing a smoke-eliminating, dust-removing, energy-saving combustion-supporting agent, wherein, the manufacturing method of the combustion-supporting agent includes the following steps:
