Research on the combustion characteristics of anthracite and blended coal with composite catalysts

Composite catalysts composed of different proportion of chemical reagents and steel industrial wastes were used as coal-burning additives. The effects of additives on combustion characteristics of anthracite coal and blended coal were studied by thermogravimetric analysis (TGA). The results showed that appropriate amount and proportion between chemical reagents and waste slag used as composite catalysts had good performances on the characteristics of coal combustion including ignition temperature, burnout temperature and burnout index, this will improve the coal combustion efficiency and also facilitate the comprehensive utilization of steel industrial waste slag.
