Abstract

The invention discloses a coal combustion catalyst which is formed by mixing a rare earth compound, transition metal salt, alkali metal salt, alkaline-earth metal salt, an oxygen family compound and water. The coal combustion catalyst disclosed by the invention has the advantages that the coal combustion catalyst can effectively reduce energy consumption, a large thermal power unit can save 5-10 g of coal per kilowatt hour, and the boiler operating oxygen demand can be reduced by 20 percent; the coal saving rate in a medium and small-sized kiln is 5-30 percent; the combustion temperature can be improved by 150-250 DEG C. Therefore, the economic benefit is obvious; the waste gas pollution caused by coal combustion can be reduced; through adding Na2MoO4.2H2O, sodium molybdate not only has a catalytic effect, but also can realize a good corrosion inhibition effect in an aerobic or anaerobic environment; through adding C10H16N2O8 and C10H16N2O8, a very stable aqueous solution complex can be formed with alkali metal, rare earth elements and transition metal, so that a catalyst effect can be favorably and stably realized.
