Abstract:
    A bubbler assembly comprising a bubbler tube having a sleeve surrounding at least a portion thereof to define an annular space therebetween. A corrosion-inhibiting gas is introduced into the space to minimize oxidation and alkali-sulfate corrosion of the bubbler tube, or preferably the gas is moved through the space to purge the space of oxygen and alkali-sulfate corrosives, when the bubbler assembly is mounted within a mounting hole provided through a refractory wall, e.g. the bottom, of a glassmaking furnace. The bubbler assembly alternatively comprises a bubbler tube, a fluid coolant jacket mounted within the refractory wall mounting hole, and facilities for facilitating movement of the bubbler tube relative to the refractory wall, independently of the fluid coolant jacket.
