Abstract:In order to investigate the reasonable blending plan of bituminit and anthrancite, the combustion and radicals of single coal as well as the combustion of blend coal were analyzed with thermal analysis device and FT-IR. The results indicated that the quantity of -OH was found to be reduced with deepening of degree of coalification, while that of -CH3 was found to be increased. A positive effect of relatively inferior combustion property bituminie on facilitating the combustion of anthranctie was noticed. Meanwhile, ideal combustion property of blend coal can also be obtained by the blending of bituminite and anthrancite with similar functional group structure.
