Problems solved by technology

For these reasons, this desulfurizer has no practical value, and this desulfurizer can only desulfurize and cannot improve the combustion efficiency of coal, so it is necessary to add a combustion accelerator, which is troublesome to operate

Abstract

The invention provides a coal-fired additive, which comprises the following components in percentage by weight: 3-15% of borax, 1-10% of sodium hydroxide, 0.2-2.5% of a barium catalyst, 5.5-32% of calcium peroxide, 5-45% of propylene glycol, 15-68% of gluconic acid and 5.5-16% of glycerol. By adopting the coal-fired additive disclosed by the invention, the combustion efficiency of coal can be remarkably improved, the dust emission is reduced, the emission of sulfide is reduced, the slag attached to the furnace wall is effectively removed, and the internal corrosion of combustion equipment is prevented, so that the service life of the equipment is prolonged.

Description

technical field [0001] The invention relates to a coal-burning additive, more specifically, relates to a coal-burning additive capable of improving coal combustion efficiency, reducing dust emission and reducing SO2 emission. Background technique [0002] At present, there are abundant deposits, but there are problems such as inconvenient use, serious pollution, and low combustion efficiency. It is a major waste of energy that coal cannot be fully burned to exert its combustion heat, and the sulfides in the exhaust gas produced by coal combustion corrode coal-fired equipment and cause serious pollution to the atmospheric environment. Therefore, how to improve the combustion efficiency of coal and effectively remove sulfide has become an urgent problem to be solved. To improve a large number of coal-fired equipment to improve its combustion efficiency requires a huge investment, which is difficult to achieve in the short term. At present, the method of adding combustion acc...
