Abstract
A glass manufacturing apparatus is disclosed including a vessel configured to convey molten glass, a conduit extending from the vessel, the conduit including a distal end with a concave heating member joined thereto, a first electrical flange joined to the conduit, and a second electrical flange joined to the concave heating member. A method of preventing devitrification of a molten glass forming material is also described.
Claims23
A glass manufacturing apparatus, comprising:
- a vessel configured to convey molten glass;
- a conduit extending downward from the vessel, the conduit comprising a distal end comprising a concave heating member joined thereto:
- a first electrical flange joined to the conduit;
- and
- a second electrical flange joined to the concave heating member.
(canceled)
A glass manufacturing apparatus, comprising:
- a molten glass delivery vessel;
- a conduit extending from the molten glass delivery vessel, the conduit comprising a proximal end joined to the molten glass delivery vessel and a distal end with a conical heating member extending from the distal end toward the molten glass delivery vessel;
- and
- an electrical flange joined to the conical heating member.
-25. (canceled)
A method of preventing devitrification of a molten glass forming material, comprising:
- flowing the molten glass forming material through a conduit, the conduit comprising a concave heating member joined to the conduit and extending around at least a portion of a length of the conduit;
- establishing an electrical current in the conduit and the concave heating member between a first electrical flange joined to the conduit and a second electrical flange joined to the concave heating member, the concave heating member conductively heating the at least a portion of the length of the conduit.
