Division 25

BAT for primary emissions from sinter strands is to reduce emissions of polychlorinated dibenzodioxins/furans (PCDD/F) and polychlorinated biphenyls (PCB) by the injection of adequate adsorption agents into the waste gas duct of the sinter strand before dedusting with a bag filter or advanced electrostatic precipitators when bag filters are not applicable (see BAT 20).

The BAT- associated emission level for polychlorinated dibenzodioxins/furans (PCDD/F) is < 0,05 – 0,2 ng I-TEQ/Nm³ for the bag filter and < 0,2 – 0,4 ng-I-TEQ/Nm³ for the advanced electrostatic precipitator, both determined for a 6 – 8 hour random sample under steady-state conditions.
