摘　　要：近年来,混煤燃烧在世界范围,特别是在中国得到了广泛的应用。针对这种情况,选定4种单一煤种及其9种混合比例的混煤进行了试验研究,得到了着火温度、可燃性指数Wmax/Ti2和综合燃尽指数SN等数据,确定了几种燃烧特性较好的混合比例的混煤。In recent years coal mixtures are widely used in world, and especially in China. In view of these circumstances, 4 individual coal categories and mixtures of them blended in 9 different proportions were chosen for experimental studies. Data concerning ignition temperature, combustibility index Wmax/Ti^2 and bum-off index SN were herewith obtained. Consequently, a few blending proportions, featured by relatively good combustion properties, were fixed for usage.
