Abstract

The invention relates to a coal-saving combustion improver and a preparation method thereof. The coal-saving combustion improver comprises, by weight parts, 2-4 weight parts of cerium nitrate, 20 weight parts of sodium carbonate, 7-9 weight parts of potassium dichromate, 40 weight parts of diatomaceous earth and 50 weight parts of water. According to the coal-saving combustion improver and the preparation method thereof, not only is the production process simple and convenient, but also raw material varieties and compositions are selected rationally in the formula, so that the raw materials are mixed evenly and have effects gradually along with the rise of the combustion temperature in the coal combustion process, and the combustion-supporting duration is long. High molecular compounds in coal are fully burned to release plenty of heat, the exhaust gas discharge is reduced, and the environmental pollution is reduced.

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 preparation 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. Only from the perspective of improving oxygen supply, the instantaneous effect is strong, but the duration is short, and the coal saving effect is not ideal; [0005] 2....
