采用热力学平衡计算和管式炉实验的方法对垃圾焚烧中氯化物对铜迁移转化特性的影响进行了研究。热力学平衡计算和实验研究结果表明，氯化物的形态、含量及焚烧温度对铜的迁移转化特性有显著影响。无论是有机PVC还是无机NaCl对铜都有氯化作用，使其生成易蒸发的CuCl，从而促进铜向飞灰中的迁移分布，NaCl的影响大于PVC。焚烧温度、氯化物的热解特性与焚烧方式协同作用影响铜的迁移转化特性，随温度升高 PVC 的氯化作用减弱而 NaCl 的作用增强。焚烧时间对 PVC 没有显著影响，对 NaCl 的影响显著。扫描电镜-能谱分析(SEM-EDS)结果显示，添加PVC时铜在底渣中以氧化物的形态存在，而添加NaCl时铜以氧化物和氯化物的形态共存，飞灰中铜以氯化物的形态存在于小颗粒中。

The effects of chlorides on the Cu partitioning and speciation in the municipal solid waste (MSW)incineration was investigated using thermodynamic equilibrium calculation and a simulated tubular furnace experiment. The thermodynamic calculation and experimental results show that the form and amount of chloride and the temperature impacted significantly on the Cu partitioning and speciation. Both organic PVC and inorganic NaCl could chlorides copper to form volatile CuCl, as a result, it promotes Cu distribution in fly ash. The NaCl had a more significant effect than the PVC does. The combustion temperature and properties of pyrolysis and combustion of chloride affected Cu partitioning and speciation synergistically. As the temperature increased, the chlorization effect of PVC decreased, whereas the chorization effect of NaCl increased. Incineration time had apparent influence on NaCl but almost no influence on PVC. The results of SEM-EDS show that Cu is present as oxide in bottom ash with PVC addition, while with NaCl addition, Cu as oxide and chloride. The element of Cu in the fly ash is in the form of chloride in small particles.
