摘　　要：通过研究不同气氛、不同时间下医疗废物中氯的析出变化,考察了气体流速、焚烧温度和不同比例的水蒸气对医疗废物中氯析出的影响。研究表明,空气流速对氯析出具有明显影响;氯的析出随温度增加而增加;O2较空气、空气与水蒸气的混合气更能促进HCl生成;水蒸气的参与提高了氯的析出率。综合各因素,在医疗废物焚烧过程中,当温度控制在900—950℃,空气过剩系数在1.5,医疗废物含水率达到50%,适当通入富氧时,能使医疗废物在焚烧过程中氯的析出最大。The effects of gas flow rate, combustion temperature and different ratios of steam on chlorine removal from medical wastes were examined on medical wastes incineration process. Results showed that gas flow rate have increased effect on chlorine release, chlorine release rate at 750-950 ℃ reaches to 85 % obviously higher than lower temperatures, chlorine release rate in the oxidizing atmosphere was higher than in the inert atmosphere or steam, or steam and their mixture gas atmosphere, chlorine removal rate increase as steam was added.
