摘　　要：卤族元素在燃烧时会影响CO的氧化和NO的生成。本文通过化学平衡方法分析了H2O和HCl对于CO氧化的协同效应,在非均匀布风流化床中进行了PVC塑料与煤或半焦的混烧试验,测量了CO和CH4的排放特性,从而从理论上和实验上证明了HCl对CO氧化的抑制作用。并给出了今后研究的方向和问题。The effects of halogens on the oxidation of carbon monoxide (CO) and nitrogen oxide (NO) emissions are discussed by summarizing the previous researches. The synergies of H2O and HCl on the oxidation of CO are analyzed by the method of chemical equilibrium. The co-combustion of PVC plastic and coal or char is studied in an ICFB. And the emissions of CO and CH4 are measured. The computational study and experimental investigation both show HCl can inhibit the oxidation of CO. The problems needed to be studied in the future are also presented.
