摘　　要：对现行的几种经济细度的定义和决定方法进行了分析 ,以广西合山电厂 4台高压锅炉为例 ,比较了 3种方法的优缺点 .同时 ,还研究了煤粉细度与炉膛出口烟温、飞灰磨损的关系 ,得出了一些有意义的结论 .The definition of economic fineness of coal_dust and its determining methods in several currently used codes and specifications are analyzed. And taking the four high_pressure boilers of Heshan Power Plant in Guangxi Region for example, the advantages and shortcomings of the different methods are compared each other. Meanwhile, the relations between finenesses of coal_dust, temperatures of flue gas at boiler exit and fly ash erosion are studied. Finally, some significant conclusions are obtained.

关 键 词：煤粉细度 经济性 飞灰磨损 燃煤锅炉
