PREPARATION AND USE METHOD OF COAL CARBON EFFICIENT ENERGY-SAVING DESULPHURIZATION ADDITIVE

摘要

A method of preparation for high-efficiency and energy-saving desulfuration additive of coal, which is characterized in that its components comprise the following materials by weight percentage: 30-40% ammonium perchlorate, 5-12% manganese carbonate, 5-12% zinc oxide, 10-23% sodium permanganate, 3-9% manganese dioxide, and 20-35% calcium phosphate primary. The above materials are mixed and broken up, and screened with sieve of 250-300 meshes. A method of application for high-efficiency and energy-saving desulfuration additive of coal in that the additive is fully mixed with coal for firing in furnace, wherein the weight ratio between the additive and the coal is between 3 to 1000 and 8 to 1000. While the coal is fired, the additive not only supports combustion to reduce coal consumption but more effectively decreases harmful gases in the furnace by firing, removing and defusing impurities and harmful substances in the coal so that no harmful substances are formed and discharged.
