Abstract

The invention relates to the technical field of coal combustion, in particular to a coal combustion cleaning catalyst. The coal combustion cleaning catalyst is prepared from the following components:a solvent, an oxygen-containing free radical component, a permeating component, a catalytic cracking component, a function surface component and a metal organic chelate. The coal combustion cleaning catalyst can promote oxygen-enriched combustion of coal, and can further reduce emission of dust, carbon monoxide and carbon dioxide; and the coal combustion cleaning catalyst can further reduce generation of coke scale in coal-consumed boiler and decoke and descale, improve a working condition of a combustor, improve the production safety, and reduce the operation and maintenance costs of the coalcombustion cleaning catalyst.

Description

technical field [0001] The invention relates to the technical field of coal combustion, in particular to a coal combustion cleaning catalyst. Background technique [0002] The combustion efficiency of coal in the prior art is generally lower than 85%. At the same time, problems of sulfur dioxide, nitrogen oxides, and smoke pollution will also be generated during the combustion process. Improving the combustion efficiency of coal can effectively save coal resources. The common method to improve coal combustion efficiency is to let coal undergo oxygen-enriched combustion. Due to the existence of objective factors, sulfur dioxide and nitrogen oxides are bound to be produced during coal combustion. The traditional The method is to use adsorbents to adsorb and filter sulfur dioxide and nitrogen oxides to prevent them from entering the atmosphere to pollute the air. The amount of sulfur dioxide and nitrogen oxides produced during coal combustion is large, which requires a large am...
