ABSORPTION OF SULFUR DURING FILTRATION COMBUSTION OF SULFUR-CONTAINING SOLID FUELS AND WASTE BY CALCIUM-CONTAINING SORBENTS

The analysis of the results of studies on the absorption of sulfur using marble additives in the charge during filtration combustion of various types of sulfur fuels and waste was carried out. It has been shown that when fuels containing metal sulfides and organic sulfur compounds are burned, the addition of marble can significantly (2–3 times) increase the proportion of sulfur passing into solid combustion products, whereas for fuels containing metal sulfates, a similar addition of marble increases the sulfur content in the solid residue by only 25–30%.
