摘　　要：对电站中储式制粉系统细粉分离器进行了模化实验,实验就不同抽气率及加装惯性分离装置对旋风分离器的效率及抽出细粉的粉量和细度进行了研究。实验结果表明,装有惯性分离装置的下抽气旋风分离器不但可以提高传统旋风分离器的效率,并且能抽出粉量和细度能满足锅炉超细煤粉再燃要求的超细煤粉。The simulate experiments of the pulverized coal classifier in the storage milling system of power plant is presented. The experiments are carried out to determine the affection of different rate of abstracting of air and the inertial separation equipment to the efficiency of the pulverized coal classifier and the quantity and slenderness of the pulverized coals that abstracted. The results show that extracting air from pulverized coal classifier with a inertial separation equipment not only can improve the efficiency of the pulverized coal classifier, but also can extract enough micro- pulverized coals for micro- pulverized coals reburning in boilers.
