循环流化床锅炉的物料循环系统是实现燃料煤完全燃烧的关键环节，也是循环流化床锅炉的特性之一，它主要由旋风分离器、立管和返料器组成，其中返料器工作的正常与否，直接制约着锅炉燃烧是否稳定，并影响着锅炉的长周期安全运行。%The materials circulating system is crucial for complete fluidized bed boilers and it is also one characteristic of CFB boilers. combustion of coal in circulating This system is mainly consisted of cyclone separators, vertical pipes and loop - seal recycle devices. Operation of the loop - seal recycle devices directly conditions the stability of boilers combustion and influences the long period and safe running of boilers.
