摘　　要：以义马粉煤为研究对象,采用热分析技术研究了MnO2对粉煤燃烧特性的影响。研究结果表明,添加MnO2对粉煤的燃烧特性有显著的影响,影响程度与MnO2的用量有关。在实验条件下,MnO2的加入量对燃点没有明显的影响,但对燃烧完全程度及达到最大燃烧速率时的温度具有明显的改进效果。The effect of MnO2 on the combustion characteristic of Yi ma pulverized coal is studied by using thermogravimetric analysis. The results reveals that MnO2 significant effect the combustion characteristic od pulverized coal. The impact is related to the amount of MnO2. Results based on laboratory test indicate that amount of MnO2 would little impact for flash point, nevertheless, it obviously effect for combustion degree and the temperature of maximum combustion rates.
