Problems solved by technology

However, due to the different types of coal, the combustion performance is different, and the thickness of the combustion layer is different, the combustion method is different, and the combustion appliances are different, which often affects the combustion speed. It will also be incompletely oxidized, resulting in dry distillation gas or carbon monoxide, and carbon particles, so that the fuel cannot be fully Combustion releases enough heat to affect coal combustion performance

Abstract

The invention discloses a coal combustion catalyst and a preparation method thereof; the coal combustion catalyst is made from, by weight, 20-30 parts of quick lime, 10-20 parts of bauxite, 4-7 parts of ferric chloride, 2-4 parts of calcium chloride, 6-10 parts of tourmaline powder, 3-5 parts of rare earth oxide or rare earth chloride, 2-4 parts of ethanolamine, 3-5 parts of a surfactant, 2-3 parts of a co-catalyst, 6-9 parts of a penetrant, 4-6 parts of a dispersant, and 40-60 parts of water. The coal combustion catalyst is prepared by proportionally mixing the quick lime, bauxite, ferric chloride, calcium chloride, tourmaline powder, ethanolamine, the surfactant, the co-catalyst, the penetrant, rare earth oxide, rare earth chloride and water; the coal combustion catalyst allows full contact between coal and oxygen; redox is achieved under the catalytic action; quick combustion and full combustion of coal are achieved; coal combustion efficiency is improved, pollutant emission is decreased, and clean combustion of coal is achieved accordingly.

Description

technical field [0001] The invention relates to the field of coal combustion, in particular to a coal combustion catalyst and a preparation method thereof. Background technique [0002] During the combustion process, coal needs to be in contact with oxygen in the air to oxidize carbon into carbon monoxide or carbon dioxide and release heat. However, due to the different types of coal, the combustion performance is different, and the thickness of the combustion layer is different, the combustion method is different, and the combustion appliances are different, which often affects the combustion speed. It will also be incompletely oxidized, resulting in dry distillation gas or carbon monoxide, and carbon particles, so that the fuel cannot be fully Combustion releases enough heat to affect the combustion performance of coal. Contents of the invention [0003] In view of this, the object of the present invention is to provide a coal combustion catalyst and a preparation metho...
