Claims10
Apparatus for indirectly heating molten glass-carrying passages, feeders and feeder heads comprising a structural refractory material having a resistivity greater than the resistivity of molten lime-sodium glass, said refractory material forming said passages, feeders and feeder heads, and a plurality of electrode means in contact with and mounted exteriorly of said refractory material forming said passages, feeders and feeder heads and means to supply said electrode means with electrical energy via independent heating circuit means.
Method for indirectly heating molten glass-carrying passages, feeders and feeder heads made of a structural refractory material having a resistivity greater than the resistivity of molten lime-sodium glass which comprises exteriorly contacting said refractory material forming said passages, feeder and feeder heads with a plurality of electrodes and passing heating current directly through said refractory material via said electrodes whereby said refractory material acts as a resistance heating conductor without direct contact between the molten glass and said electrodes.
