ABSTRACT:
An arc furnace fume collection system has a plurality of duct lines leading to a common duct that leads to a baghouse for filtering dust. The supplemental duct lines have high pressure fans, blowers, or compressors and join one of the other duct lines through a nozzle. The nozzle connection acts as a venturi to supplement the pulling power of a common exhaust fan downstream of the baghouse filter.
