ABSTRACT:
A push-pull exhaust scavenging system for removal of noxious fumes emanating from the mouth of metalurgical vessels known as converters. The converter, configured as a drum disposed for rotation about the elongate longitudinal axis includes a mouth opening and an instrumentality for moving the converter mouth from a plurality of positions so as to effect the addition and deletion of substances within the converter. Conventional gas hood in overlying registry with the converter mouth allows exhaust gases to be scavenged from the converter during one state of the converter process, but rotation of the converter mouth away from the conventional gas hood requires the exhaust and intake manifold according to the instant invention including positive and negative air flow for forcing air into the exhaust conduit system. An additional exhaust conduit is provided above the conventional gas hood for further improved scavenging.
