摘　　要：试验研究不同煤种燃烧率和煤粉粒度组成关系。研究表明烟煤存在最佳燃烧率的粒度组成值。当考虑到磨煤能量消耗,无论是烟煤还是无烟煤,都有合适的粒度组成范围,根据研究结果推荐值是将煤粉-0.074mm比例定为60%～80%。同时也初步探讨了煤粉燃烧率与镜质组反射率之间的关系,得到了一些有益的结果。The relationship of combustion efficiency and pulverization coal size distribution by using the different kinds coal is studied. Result is shown that, a best value of bituminous size distribution was existed for gained the high coal combustion efficiency. Also the best value of coal size distribution was existed for bituminous and anthracite if the coal grinding consumption was accounted. Recommend value is 60% to 80% pulverized coal size below -0 074 mm based on this study. The relationship of coal combustion efficiency and reflectivity of vitrinite was also studied.
