Abstract

Based on deep analysis of technological data of the sinterplant and experiments, the chlorine input in the sinter mix wasidentified as the main factor influencing the dust precipitationefficiency in ESP. On the basis of this perception two differentways of emission control where successfully worked out andrealized: first, the control of chlorine input with the charge,second, the selective filter dust removal. The annual average ofdust content in clean gas was reduced from 49.7 mg/m3 (2004)to 24.6 mg/m3 (STP) (2006). In parallel this measures lead to areduction of Dioxin emission level < 1 ng/m3 pt (STP).
