Abstract
A discharging device is provided at the bottom of a glass melting furnace. The device includes an inductively heated outlet unit including a compression flange having an inlet opening and an outlet pipe extending from the compression flange to form therewith a unit having a T-shaped cross section. The outlet pipe is penetrated by an outlet channel communicating with the inlet opening. The outlet pipe projects downwardly out of an opening in the furnace. An outlet block is seated on the compression flange and has an outlet channel flush with the inlet opening of the compression flange. An annular supporting flange supports the outlet unit from the bottom against the compression flange, with the annular supporting flange being supported by a bottom carrier plate of the furnace and the outlet pipe of the outlet unit projecting through an opening in the annular supporting flange. A thermal and mechanically deflecting creep barrier is disposed for stopping creep flow of glass melt between the compression flange of the outlet unit and other components of the furnace, including the outlet block, in contact with the compression flange, by freezing the melt and causing a pressure loss in the creep flow with respect to static pressure of the melt in the furnace.
