Thermogravimetric investigation on co-combustion characteristics of tobacco residue and high-ash anthracite coal

► Effects of the mixed proportion between coal and tobacco residue on the combustion process were studied. ► The incorporation of tobacco residue can improve the combustion characteristics of high-ash anthracite coal. ► The ignite temperature and ignite index increases with the increase of tobacco residue content in blends. ► Co-combustion of tobacco residue and high-ash anthracite coal as fuel is feasible.
