Casthouse emission control system

Patent ·
OSTI ID:5878056
;
An emission control system for controlling the emissions released from the pig iron and slag released from a blast furnace and through the troughs in a casthouse. The system comprises tap hole cover means for covering the first end of the main iron trough and for evacuating emissions from the pig iron and slag flowing through the first end of the main iron trough. The tap hole cover means in flow communication with scrubber means for cleaning emissions. Removable cover means for covering the second end of the main iron trough and for evacuating emissions from the pig iron and slag flowing through the second end of the main iron trough. The removable cover means in flow communication with scrubber means for cleaning emissions. Main iron runner cover means for covering the main iron runner to prevent the escape of emissions into the ambient air. Slag runner cover means for covering the slag runner to prevent the escape of emissions into the ambient air. Iron runner emission evacuation means disposed at the iron exit end of the iron runner for evacuating emissions from the pig iron and slag flowing through the iron exit end. The iron runner emission evacuation means in flow communication with scrubber means for cleaning emissions.
