摘要: The fly ash used in this study was collected from a bag filter medical waste rotary kiln incineration system, using lime and activated carbon injection followed by their collection as mixed ash. Experiments were conducted on quartz tube, heated laboratory-scale horizontal tube furnace, order to the effect of temperature nitrogen flow rate removal PCDD/Fs. Results indicated that PCDD/Fs mostly removed desorbed very little into flue gas under thermal treatment especially when heating higher than 350 °C, dechlorination destruction reactions took important part However, terms rate, 4 cm s(-1), efficiency decreased dramatically main contributors P(5)CDF, H(6)CDF H(7)CDF gas, with enhanced rate.
