Abstract:The effects of Cu and Cl elements from raw materials on the emission of PCDD/Fs were carried out in this paper. The results show that the contents of Cu and Cl elements affectsignificantly the emission of PCDD/Fsduring the iron ore sintering process. Compared with the based test, when the content of Cu element increased from 0.02% to 0.04%, the concentration of PCDD/Fs was enhanced(TEQ) from 0.55 to 0.69 ng/m3; while the concentration of PCDD/Fs was enhanced(TEQ) from 0.55 to 0.82 ng/m3 when the content of Cl element increased from 0.04% to 0.06%. It is an effective way to reduce the emission of PCDD/Fs by adding urea in the granules. The emission of PCDD/Fs could drop by 65% when 0.035% urea was added into the granules.
