摘　　要：在一个模拟流化床反应器中,研究160～600℃下水蒸气的存在对CaO脱除HCl的影响。采用X射线衍射仪(XRD)分析产物成分,SEM电镜对产物进行微观结构分析,从而分析CaO的脱氯性能。实验结果表明:随着水蒸气浓度增加,HCl的净化效率呈现一个先下降后上升的趋势。XRD分析表明,产物的主要成分为CaClOH,在净化效率达到一定量时,产物中生成了Ca(OH)_2;SEM电镜观测到中低温下产物的针状形态以及高温条件下稀松产物层的生成。The effect of steam to HC1 removal has been investigated in the temperature range from 160℃ to 600℃ in a fluidized-bed incinerator. Scanning Electron Microscope （SEM） and X-ray diffraction （XRD） are used to detect the morphological structure and the components of the products. The results show that： As the steam concentration increases, the removal efficiency decreases at first and then increases. XRD analysis show that the main components of the product is CaClOH, and Ca（OH）2 is produced when the removal efficiency is up to a high level. SEM analysis finds that the spieulate structure of the product at mid- low temperature and the porous product layer at high temperature.
