摘　　要：循环流化床脱硫是目前国内应用最多的(半)干法脱硫技术,但经过多年的运行也暴露出诸如系统可靠性差、循环灰装置易堵塞、湿壁、系统能耗大、运行费用高、脱硫率低等问题。本文就循环流化床脱硫工艺在实际运行中存在的问题进行了分析讨论。Circulating fluidized bed desulfurization means semi-dry desulfurization technology which is used widely in the country,but it shows many problems,such as weak system reliability、circulating ash equipment easily jammed、wetted wall、high energy consumption of system、high running expense、low desulfurization rate,and so on.This paper makes analysis on the common problems existed in circulating fluidized bed desulfurization process.
