摘　　要：采用热分析仪对福建无烟煤和玉米芯的混合燃烧特性进行了研究,结果表明,无烟煤混合玉米芯后,其着火提前,燃烧和燃尽特性得到改善,但随着玉米芯混合比例的增加,无烟煤后期燃烧特性改善并不明显;此外,采用Coats-redfern法计算了无烟煤和玉米芯不同比例混合燃烧的活化能E,计算结果表明,无烟煤混合玉米芯后,其活化能E降低,但活化能的大小与玉米芯的比例大小无明显关系.玉米芯对无烟煤的燃烧主要起"引燃"作用.ABSTRACT The co-firing characteristics of Fujian anthracite and corn cob blends was studied with thermogravimetric technique. The results show that the characteristics of ignition, burning and burn-out of Fujian anthracite were improved added with corn cob. However, with proportion of corn cob increased, the improvement of the latter combustion characteristics of anthracite is little. Besides, the activation energy E was calculated by using Coats-Redfern method. It shows that E is decreased added with corn cob. However, the value of E hasn＇t the obvious matter with the proportion of corn cob. The effect of corn cob on anthracite firing is mainly improving the ignition characteristics.
