Analysis on fault reasons of coal pulverizing system of 600MW boiler and treatment countermeasures

Abstract

Abstract: Abstract:The fault often occurred in coal pulverizing system of the 600MW boiler in Fujian Zhangzhou Houshi Power Plant, and which threatens the save and economic operation of the unit in some degree. The common fault types of the coal pulverizing system were expounded, the reasons of the faults were analyzed, and the treatment countermeasures were proposed. The experiences of the power plant provide reference for other power plants to treat similar faults.

Key words: Keywords:600MW boiler, medium speed mill, coal feeder, structure, working principle, fault phenomenon, treatment countermeasure
