Problems solved by technology

However, when coal is burned, in addition to sulfur being oxidized into sulfur dioxide, nitrogen is also converted into nitrogen oxides, and coal combustion also produces soot
Sulfur dioxide, nitrogen oxides and soot will all cause environmental pollution, and this additive can only reduce the production of sulfur dioxide, which needs to be improved

Abstract

The invention relates to an efficient coal combustion-supporting additive and a preparation method thereof. The composition is prepared from the following raw materials in parts by weight: 3-6 parts of dolomite, 2-5 parts of carbide slag, 1-4 parts of calcium lignosulphonate, 2-5 parts of olivine powder, 1-3 parts of magnesium carbonate mineral powder, 1-3 parts of zirconium powder, 1-3 parts of nano shell powder, 0.5-1.5 parts of strontium carbonate, 0.5-2 parts of anhydrous borax, 1-2 parts of potassium chromate and 1-3 parts of a cyclohexane methyl acrylate-polyethylene glycol monoallyl ether-lecithin-vinyl glucopyranoside copolymer. The invention further discloses a preparation method of the efficient coal combustion-supporting additive. The efficient coal combustion-supporting additive disclosed by the invention is remarkable in combustion-supporting effect, and can reduce sulfur dioxide, nitric oxide and smoke dust generated during coal combustion at the same time, so that the purpose of protecting the environment is achieved; in addition, the combustion efficiency can be improved, and the service life of equipment such as a boiler can be prolonged.

Description

technical field [0001] The invention relates to the technical field of coal fuel additives, in particular to a high-efficiency coal combustion-supporting additive and a preparation method thereof. Background technique [0002] In recent years, with the advancement of global industrialization, environmental issues and energy issues are still the "two mountains" that hinder social development. In the face of increasingly tight energy resources and environmental protection requirements, how to improve energy thermal efficiency and reduce air pollutant emissions is the goal of technical workers in the energy field. Coal is the primary energy source in my country, and more than 85% of the carbon-based fuels used for thermal power generation, industrial boilers, industrial kilns and household stoves are directly burned. However, when coal is burned, it will produce a large amount of sulfur dioxide, nitrogen monoxide, and smoke, polluting the environment. In addition, when the ex...
