Disclosed is an apparatus for conditioning molten glass. The apparatus includes a connecting tube assembly having a conduit for conveying the molten glass, the conduit including at least two flanges and a sealing member disposed between the at least two flanges around an outer peripheral region of the flanges, thereby forming an enclosed volume between an outer wall of the conduit, the at least two flanges and the sealing member. An atmosphere within the volume may be controlled such that a predetermined partial pressure of hydrogen or a predetermined partial pressure of oxygen may be maintained within the volume. A current may be established between the at least two flanges to heat the conduit.

The present disclosure relates to a method for cooling a component of a glass melting plant that contacts a glass melt, the corresponding cooling device, as well as the system of the cooling device and the cooled component itself. The method provides that a pipe with an open pipe end at least on one pipe section is introduced into an open cavity in the component with the formation of a peripheral annular space, and a cooling medium is introduced through the pipe into the cavity and is deflected at the base of the cavity, flows back in the annular space, and flows out of the cavity. In its pipe section introduced into the cavity, the pipe has a constriction and has perforations through the pipe walls in the region of the constriction, whereby the cooling medium is accelerated in its passage through the constriction in the inside of the pipe, and a portion of the cooling medium flowing back from the annular space is aspirated into the inside of the pipe.
