|a The co-processing of hazardous waste in a cement kiln can eliminate a large quantity of hazardous wastes, but the excessive existence of chlorine will affect not only the operation of a cement kiln but also the quality of cement products. In this study, the mixtures of hazardous waste incineration residue and raw meal were incinerated in a high temperature tubular furnace. The distribution ratio of chlorine in flue gas, clinker and fly ash under different experiment conditions was obtained and the influence of the co-processing conditions on chlorine evolution and transformation was studied. The results showed that chlorine mainly existed in flue gas and clinker, and only less than 1% of chlorine existed in fly ash. The incineration temperature had a significant influence on the distribution of chlorine. The higher the incinerating temperature, the greater the distribution ratio of chlorine in flue gas and fly ash. The proportion of chlorine in all parts remained basically unchanged while the temperature was higher than 1300°C. With the increase of the retention time, the proportion of chlorine released into the flue gas increased. The distribution ratio of chlorine in each part remained unchanged after about 30 minutes. There were four stages of the rate of chlorine release. In addition, the chlorine content of the sample had little effect on the partition of chlorine. Some suggestions on the co-processing of hazardous waste in a cement kiln are put forward based on these experimental results
