摘　　要：循环流化床锅炉的入炉煤粒度要求较严格,对锅炉负荷、燃烧效率、水冷壁磨损等影响较大,因此输煤系统筛分设备在设计选型、运行维护等方面均是关键环节,通过对筛子的实际运行问题分析,得出必须对筛子进行技改,技改后设备运行状况良好,有效地控制了入炉煤的粒度,有利于锅炉安全稳定运行。Circulating fluidized bed boiler size of coal into the furnace more stringent requirements, the boiler load, combustion efficiency, water wall wear a greater impact, so the coal handling system of screening equipment in the design, operation and maintenance is the key link, through the actual operation of the sieve analysis, comes to the conclusion that the transformation of the sieve, the operating conditions of the equipment transformation after a good, effective control of the particle size of coal into the furnace, is conducive to the safe and stable operation of the boiler.
