Abstract

The invention relates to a coal-saving combustion improver and a production method thereof. The coal-saving combustion improver comprises the following ingredients by weight: 40 to 60 parts of furnace slag, 10 to 15 parts of magnesium chloride, 15 parts of potassium chlorate, 35 parts of sodium nitrate, and 30 parts of aluminum sesquioxide. The coal-saving combustion improver and the production method have the advantages that not only is the production technology simple and convenient, but also the types and the contents of raw materials in the formula are reasonable; the raw materials are uniformly mixed, and the mixture functions gradually along with the combustion temperature rise during the combustion process of coal, so that the combustion-supporting duration is long, and coking can be prevented effectively; moreover, high-molecular compounds in coal are combusted sufficiently to release a great amount of heat, and reduce waste gas emission and environmental pollution.

Description

technical field [0001] The invention relates to the technical field of energy saving and emission reduction, in particular to a coal-saving combustion aid and a production method thereof. Background technique [0002] Coal is closely related to people's production and life. However, coal is a non-renewable resource. With the advancement of industrialization, the demand for coal is also increasing. Therefore, saving coal is an important task at present. In addition, coal often produces a large amount of soot particles and harmful gases during the combustion process, which is not conducive to environmental protection. [0003] Adding combustion accelerants to coal is an important means of energy saving and emission reduction, but there are still the following problems in combustion accelerants: [0004] 1. Coking is prone to occur during combustion. [0005] 2. After adding the combustion improver, the combustion duration is short, and the coal saving effect is not ideal. ...
