Abstract
A glass delivery system is disclosed having a glass conducting pipe enclosed within a refractory structure. The refractory structure is spaced about the pipe and defines a closed space for receiving therein a quantity of the glass. Heat input devices are located in the closed space for supplying heat to the pipe. The refractory structure may include heat exchange passages for circulation of a first heat exchange fluid therethrough. Means may be included for introducing a second gaseous fluid within the closed space between the refractory structure and the pipe for removing heat given up by the glass and under certain conditions the first fluid may act as an inert atmosphere or purge gas for protecting certain components of the system from deleterious ambience. The first heat exchange fluid removes a relatively greater portion of the heat energy given up by the glass than the second fluid.
