Coal combustion supporting energy-saving additive

Abstract

The invention discloses a coal combustion supporting energy-saving additive, which mainly comprises the following components in percentage by weight: 5-15% of nitrified rare earth, 5-20% of sodium chloride, 10-20% of magnesium nitrate, 5-10% of potassium permanganate, 5-10% of ammonium nitrate and the balance of water. The additive is obtained by proportioning according to the weight of the materials, dissolving while stirring and mixing uniformly. The additive is sprayed onto coal in a ratio of 1:3000-1:5000, and the additive and the coal are mixed uniformly. By adopting the nitrified rare earth and potassium permanganate as catalytic combustion supporting active ingredients of the catalytic combustion supporting and smoke eliminating additive, the coal combustion efficiency is high, the coal saving effect is obvious, and 5-20% of coal can be saved; by adopting a metal compound of rare earth, magnesium, sodium, potassium, manganese and the like as a sulfur fixing agent, the sulfur fixing and emission reducing efficiency is high, and the sulfur dioxide emission of a coal-fired boiler can be reduced by more than or equal to 30%; the adopted active ingredients are good in chemical stability and are easily dissolved into an aqueous solution; after the additive is mixed with corresponding coal uniformly, the additive can be kept stable for a long term; and the additive is relatively simple in preparation and good in popularization and application.

Description

technical field [0001] The invention relates to a coal-burning additive, in particular to a coal-burning combustion-supporting energy-saving additive. Background technique [0002] With the rapid development of my country's economy, the coal-based energy power industry has entered a period of rapid development, and the demand for coal has grown rapidly. Extensive use of coal has led to a large amount of pollution emissions, especially a large amount of sulfur dioxide emissions have seriously polluted the atmosphere. Although the use of low-sulfur coal can significantly reduce sulfur dioxide emissions, resources are limited and supply is tight, which cannot meet normal needs. my country's high-sulfur coal mines account for a large part, producing hundreds of millions of tons of raw coal each year to meet market demand, but there will inevitably be a large amount of pollutants, especially a large amount of sulfur dioxide.
