摘　　要：为研究助燃添加剂对煤燃烧特性的影响 ,选择了 5种金属的氧化物及盐类作为基本成分 ,运用正交试验方法考察了添加剂对炭粒燃烧特性的影响 ,然后根据极差分析和方差分析 ,得到了添加剂的最佳组成。本研究所推荐的添加剂能有效降低煤的着火温度 ,并提高其燃烧发热量。与某商品煤伴侣比较 ,在各种添加量时的助燃效果均优于该商品煤伴侣。For studying the effect of additive on the combustion characteristics of a coal,five metal oxides and salts were chosen as potential additive components, and by employing the cross cut experimental method,their effects on the combustion characteristics of char particles were examined.Based on the analysis of range and variance,the optimum composition of additive was then derived.Further experiments revealed that the additive with composition as proposed by this research could effectively reduce the ignition temperature of the coal and increase its calorific value during combustion.Finally, on the basis of the experiments, the mechanism of the promotion of coal combustion was discussed.
