The process
Basic oxygen converters produce a short, intense burst of hot, carbon monoxide rich gas at each blow. The gas is cooled and cleaned in a wet scrubber or dry ESP and drawn by an ID fan that is sized for the peak of the blow and built for the gas to be flared or recovered. Secondary dedusting takes the fume at charging and tapping into a bag filter.
The gas
Fume from arc, induction or reverberatory furnaces, hot and carrying fine metallic oxide dust. Temperature is handled by dilution air or a cooler ahead of the filter, and the fan sits on the clean side where possible.
Selection for this process
