Abstract

The investigation of dioxin formation mechanisms demonstrated that most part of PCDD/F formation occurs in the sinter mix during the sintering operation. This result has a direct impact on abatement strategies of PCDD/F: use ot inhibitors added in the sinter feed and study of the impact of raw materials. Trials carried out on the IRSID pilot pot and on the Charleroi sinter strand have shown that urea addition could be a promising method to reduce pollutant emissions at the sinter strand main stack: PCDD/Fs (about - 50%) and SO2.
