The invention relates to a method for eliminating black smoke generated during coal burning with papermaking waste liquor. The method has the advantages that (1) the black smoke generated during coal burning is effectively eliminated; (2) heat energy released by burning solids in the papermaking waste liquor is effectively used, the coal consumption is reduced, as for a paper mill with the yield of 100000 tons, if coal for making one ton of paper is 0.5 ton, 50000 tons of coal is consumed each year, if the adding amount of the papermaking waste liquor is 25%, the using amount each year is 12500 tons, the heating amount of the 12500 tons of papermaking waste liquor saves 4500 tons of coal, and if each ton of coal is the beforehand price which is 600 Yuan, 2700000 Yuan can be saved each year; (3) the black smoke generated during coal burning is processed with the papermaking waste liquor, meanwhile, the pulverized coal wastage rate is reduced, and the burning efficiency is improved; (4) the ...
