摘　　要：燃煤锅炉煤粉的性质对于燃烧的经济性、制粉系统某些部件和炉膛以至整个锅炉机组的工作影响较大。计算了电厂常用的2种筛号下不同煤粉颗粒的平均粒径,得到了平均粒径与相应煤粉细度的关系,可以根据单一煤粉细度筛分数据比较准确地得到煤粉的平均粒径,其对提高煤粉燃烧的经济性和锅炉效率有一定的意义。The nature of coal-fired boiler＇s coal is very important for the efficiency of combustion, some elements of milling system and extremely for the operation of the whole boiler unit. This paper presents a method of calculating the mean diameter of coal dust throughing two common screens in power plant, and gains the relation between the mean diameter and the coal fineness. The result can give a method of gaining the mean diameter exactly and rapidly.
