| 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.

| Abstract: | 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. |
