Problems solved by technology

The combustion enhancer with strong oxidant as the main raw material, although it reduces the ignition point of the material and has a certain effect on promoting combustion, but its stability is poor, it decomposes quickly after being heated, and has a short effect on the combustion system. The actual effect is limited. Disadvantages such as low desulfurization efficiency, high investment cost, and difficulty in controlling concentration

Abstract

The invention discloses a coal combustion improver and a preparation method and an application thereof, and belongs to the technical field of coal combustion. The combustion improver is composed of aleavening agent, an oxidizing agent, a catalyst, a stabilizer, a desulfurizing agent and a smoke suppressing agent, wherein the leavening agent is composed of sodium hydrogen carbonate, ammonium hydrogen carbonate and light calcium carbonate; the oxidizing agent is composed of potassium permanganate and potassium chlorate; the catalyst is composed of manganese dioxide, ferric chloride and aluminumoxide; the stabilizer is composed of biscyclopentadienyliron and 2-methylcyclopentadienyl manganese tricarbonyl; the desulfurizing agent is composed of calcium hydroxide, calcium carbonate, calcium chloride, ferrous nitrate and ferrous sulfate; the smoke suppressing agent is composed of alkyl alcohol ether, phosphate and chlorinated hydrocarbon. The combustion improver is applied to coal combustion supporting, and is low in preparation cost and obvious in effect. The combustion improver reduces the enterprise cost, has great economic benefit, reduces emission of harmful gases like sulfur dioxide and is conducive to environmental protection.

Description

technical field [0001] The invention relates to a coal-burning combustion aid and its preparation method and application, belonging to the technical field of coal-burning. Background technique [0002] China is the largest coal consuming country in the world, and it is also one of the few countries in the world whose energy consumption is dominated by coal. Since the reform and opening up, my country's economy has developed rapidly, but the problems of high energy consumption per unit of GDP and the resulting high intensity of pollutant emissions have increasingly restricted the sustainable development of my country's social economy. Therefore, energy conservation and emission reduction have become the priorities of governments at all levels Constraint assessment indicators. As an important energy-saving and emission-reducing product, the development and research of coal-fired combustion accelerants have been active in the past decade, and some products have been used in ind...
