Combustion-supporting additive for hot briquetting of lignite

Abstract

The invention relates to a combustion-supporting additive for the hot briquetting of lignite. The additive comprises the following components in percentage by weight: 1-2% of sodium dodecylsulfate, 2-3% of sodium bicarbonate, 10-20% of bonding agent, 5-10% of magnesium particles, 50-60% of pine powder, 5-20% of strong oxidant, 3-8% of sulfur-fixing agent and 3-10% of industrial salt. By utilizingthe additive disclosed by the invention, the burn-out rate of the lignite can be increased, the discharge of sulfur dioxide and carbon monoxide is reduced, and the effect of saving energy is achieved.

Description

technical field

[0001] The application relates to the field of coal-fired additives, in particular to a combustion-supporting additive for hot-pressing lignite. Background technique

[0002] With the continuous deterioration of the atmospheric environment, and in response to the country's call for energy conservation and low carbon. The entire society has paid great attention to the full combustion of coal and the reduction of emissions of harmful gases such as sulfur dioxide. The comprehensive application of environmental protection technology is one of the important ways to solve this problem. At present, the commonly used coal-fired combustion-supporting additives are important technologies to improve the utilization rate of coal-fired and reduce pollution.

[0003] All kinds of desulfurizers in the prior art or additives with combustion-supporting and coke-clearing functions are mainly composed of calcium oxide CaO, sodium carbonate Na 2 CO 3 , and certain strong alka...
