Abstract

A water cooled, off-gas collecting hood is adapted to be disposed above the open end of a metallurgical vessel into which oxygen and a hydrocarbon shielding fluid are blown through submerged tuyeres. The hood includes an elbow section at its upper end for being coupled to an obliquely downwardly extending conduit communicating with the inlet of a gas cleaning system. A water cooled flow divider is disposed across the elbow and between the upper end of the vessel and the top of the elbow for dividing into upper and lower flow paths the gases discharging from the vessel and which are redirected in the elbow laterally to the conduit.
