Abstract

A thermogravimetric analysis (TGA) of the combustion of two long-flame hard coals from the Republic of Khakassia, pine sawdust and their blends in the air stream, depending on the chemical composition and thermal characteristics of the samples, was carried out. The ignition temperature and the burn-out temperature of the coke residue of the studied samples were determined by extrapolation using the TG and DTG curves. The indices of ignition, burnout and combustion are calculated taking into account the time parameters. The ignition temperature of pine sawdust was Ti = 308 °C, the burnout temperature was Tb = 490 °C. When sawdust was added to the coals, the combustion process of the blend shifted to lower temperatures, and the ignition temperature decreased by more than 100 °C compared to the ignition temperature of the coals. The energy -efficient compositions of blends that ensure their high combustion characteristics are determined
