    Abstract: Iron ore sintering is one of the important emission sources for PCDD/Fs. This paper summarized formation mechanisms of PCDD/Fs in sintering process and the emission profile of PCDD/Fs in typical sintering stack gas. Key influencing factors of PCDD/Fs formation, including temperature, time, oxygen concentration and other conditions in raw material composition were analyzed. Reduction technologies of PCDD/Fs emission were also suggested in this paper. Finally, it provided analysis and outlook on the current emission of PCDD/Fs from iron ore sintering industry in China and several developed countries. It is aimed to provide reference for the management and reduction of emission of PCDD/Fs in the iron ore sintering industry in China.
