The invention relates to composite sintering catalyst which is made of, by weight percent, 3-12% of carboxymethyl starch, 20-60% of borax, 10-35% of dextrin, 5-10% of slaked lime, 10-30% of calcium bentonite and 5-15% of lignin. By the aid of the composite sintering catalyst, on the basis of not changing sintering components and sintering technology, the sintering process can be greatly improved,thermal utilization rate of fuels can be increased, consumption of the fuels is greatly reduced by 5-10%, reactivity of the fuels is enhanced, permeability of beds of material is improved, the speed of vertical sintering is increased, utilization coefficient of sintering is increased, the quality of sinters or refectories is improved, yield is increased by 3%-5%, and sintering cost is reduced.
Description
technical field [0001] The invention relates to a fuel combustion aid, in particular to a composite sintered catalyst. Background technique [0002] my country is a big coal-producing country, but also a big coal-consuming country. In various consumptions, coal or coke dominates. For example, coal or coke is mostly used as fuel for sintering of minerals or refractory materials, and in a considerable For a long time, the energy structure dominated by coal or coke will not change. But the resulting environmental pollution is also very serious. Against the backdrop of global warming and rising calls for emission reductions, for developing countries, improving energy utilization efficiency and reducing unnecessary energy waste is a relatively good, fast-acting, and practical way to reduce emissions . Coal-burning additives can improve the combustion characteristics of coal and increase the combustion efficiency of coal. On the one hand, it can save coal consumption, and on the...
