Abstract

The invention discloses a multifunctional coal-saving synergistic additive. The multifunctional coal-saving synergistic additive comprises, by weight, 1-10 parts of a mixed strong oxidant, 1-3 parts of a combustion improver and 1-6 parts of a sulfur-fixation antismoke agent. The mixed strong oxidant comprises potassium permanganate, potassium nitrate, sodium nitrate and potassium perchlorate. The combustion improver comprises sodium chloride and sodium acetate. The sulfur-fixation antismoke agent comprises calcium oxide, potassium carbonate, sodium carbonate, ferrous sulphate and bleaching powder. Through crushing, cooling, condensation and passivation, the multifunctional coal-saving synergistic additive is prepared. The concrete preparation processes are conventional processes and are simple and convenient. Aiming at different types of coal, the multifunctional coal-saving synergistic additive has good effects of supporting combustion and reducing SO2 and NOX discharge, is prepared from the raw materials having wide sources and low prices and has a very great popularization usage value.

Description

technical field [0001] The invention belongs to the technical field of coal chemical industry, and in particular relates to a multifunctional coal-saving and efficiency-enhancing additive. Background technique [0002] At present, coal, as the main energy source in our country, plays an irreplaceable role. So far, it can account for more than 70% of the primary energy composition. However, compared with relatively clean petroleum energy and natural gas energy, the development and utilization of coal energy cause the most serious environmental pollution, and the utilization efficiency of coal energy is also the lowest. The wave rises again”, prompting coal prices to soar. On the other hand, the storm of energy conservation and emission reduction has swept across the country, and many high-energy-consuming and high-polluting enterprises are facing closure. Enterprises must save energy and reduce consumption. However, most Chinese enterprises that are accustomed to extensive r...
