Abstract
A glass delivery system is disclosed having a central glass conducting pipe enclosed within a heat exchange structure. Heat shields reflect energy back to the pipe for reducing heat losses from the pipe and heaters are located about the pipe to add heat energy as required. Heaters which may be immersed in surrounding glass, are provided externally of the pipe at connections into and out of the pipe, and a bellows arrangement for accommodating expansion due to thermal cycling is provided in at least one of such connections. In a preferred embodiment, oxidizable refractory metals are used which may be protected from contamination by providing inert or reducing purging atmospheres or vacuum. Heat losses may also be regulated by atmospheric control of the purging atmosphere as well as control of a working fluid for the heat exchange structure. Means may be provided for shielding or insulating refractory components from intense radiation. Connectors are provided for modularizing the system and simplifying placement and removal thereof.
