摘　　要：为了研究更为合理的高炉喷吹煤混合方案,利用热重分析仪和傅里叶红外光谱对单煤的燃烧性和煤中有机官能团进行了分析,同时也对不同混煤的燃烧性能进行了研究。研究结果表明,煤中-OH官能团数量随着煤化度的加深而减少,-CH3官能团数量则随着煤化度的加深而增加。燃烧性稍差的烟煤在混煤中对无烟煤的助燃作用更强,官能团结构相近的无烟煤和烟煤搭配更易于获得燃烧性好的混煤。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 ofbituminite and anthrancite with similar functional group structure.
