Problems solved by technology
 10 parts of coal combustion catalyst, 2 parts of desulfurization agent, 3 parts of denitrification agent, 5 parts of glycerin stearate, 2 parts of polyoxypropylene polyoxyethylene glycerol ether, stir well, and then add 500 parts of heavy diesel oil , fully dissolved to obtain a solution, which is a coal combustion desulfurization and denitrification catalyst. When in use, it is atomized into an aerosol of 20-50 microns through a high-speed centrifugal atomizer, mixed with coal particles and powder, and directly enters the boiler for combustion. The combustion efficiency is increased by 15-20%, and the coal-saving rate is 20-30%. The emission of black smoke, sulfur dioxide and nitrogen oxides is reduced by 30-50%, the fouling in the furnace is reduced, and the working conditions of the boiler are significantly improved.
 5 parts of ethylene glycol diphenyl ether, 3 parts of dibenzyl oxalate, 15 parts of gas accelerator, 5 parts of dimethyl silicone oil, stir well, then add 400 parts of paraffin oil, fully stir and dissolve to obtain an emulsion, which is gas Promote additives. When in use, the aerosol atomized to 20-100 microns through the air atomizer is mixed with the raw coal powder and directly enters the furnace for reaction. The gasification speed is increased by 20-50%, the gasification conversion rate is increased by 10-30%, and coking in the furnace is reduced.
 2 parts of glycerol diethyl ether, 5 parts of dimethyl phthalate, 3 parts of polyoxyethylene lauryl ether sulfate triethanolamine salt, 10 parts of coal combustion catalyst, 2 parts of desulfurization agent, 3 parts of denitrification agent, respectively Add in batches to 200 parts of stirred water to obtain a combustion catalyst solution. When in use, the aerosol atomized to 20-100 microns by a pressure atomizer is fully mixed with pulverized coal, and after standing for 1 hour, it is directly burned in a pulverized coal furnace. The combustion efficiency is increased by 5-15%, the blackness of the flue gas is significantly reduced, the emission of sulfur dioxide and nitrogen oxides is reduced by 10-30%, there is no coking in the furnace, and the carbon residue in the coal ash is reduced by 30-60%.
