The generation of dioxin during recycling of solid waste is widely concerned. An experimental research on gasification of simulation garbage containing-high-PVC was carried out on a special designed integrated experimental platform for fluidized-bed gasification. The effects of PVC content and equivalent air ratio (ER) on feature of dioxins generation were discussed. The results show that when PVC content is 20% and ER decreases from 1.2 to 0.4

the yield and TEQ of dioxin produced per gram of PVC are decreased from 146.53 ng·g-1 and 20.71 ng I-TEQ·g-1 to 2.07 ng·g-1 and 0.31 ng I-TEQ·g-1

respectively. For the same ER 0.4 and PVC decreased from 20% to 1%

the yield and TEQ of dioxin produced per gram of PVC reduced from 23.54 ng·g-1 and 3.49 ng I-TEQ·g-1 to 2.07 ng·g-1 and 0.31 ng I-TEQ·g-1. That means that the risk of dioxin generation in gasification of the solid waste increases with PVC content

while low-air equivalent factor can suppress its generation.
