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.
Claims10
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;
- a second electrical flange joined to the concave heating member;
- and
- a thermally conductive material disposed in a volume defined between the concave heating
- member and a wall of the conduit,
- wherein a thickness of the conduit is greater than a thickness T2 of the concave heating member,
- wherein the concave heating member comprises a major end with a first diameter and a minor end with a second diameter less than the first diameter, and the second electrical flange is joined to an upper rim of the major end, and
- wherein the second electrical flange comprises a body portion with an inner edge defining an interior opening, the inner edge joined to the upper rim of the concave heating member about a circumference of the major end.

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;
- a first electrical flange joined to the distal end of the conduit;
- a second electrical flange joined to the conical heating member;
- and
- a ceramic cement disposed in a volume defined between the concave heating member and a wall of the conduit,
- wherein a thickness T1 of the conduit is greater than a thickness T2 of the concave heating member,
- wherein the conical heating member comprises a major end with a first diameter and a minor end with a second diameter less than the first diameter, and the second electrical flange is joined to an upper rim of the major end, and
- wherein the second electrical flange comprises a body portion with an inner edge defining an interior opening, the inner edge joined to the upper rim of the conical heating member about a circumference of the major end.
