Abstract

A glass transport system configured to mitigate or stop damaging glass leaks by incorporating silica-containing structural components or introducing silica-containing materials to the advancing glass leak flow to cause the molten glass to interact with silica in the silica-containing material and increase the viscosity of the molten glass sufficiently to slowdown or stop the flow of the glass leak.

First claim

What is claimed is:

1 . A method of mitigating glass leak in a glass transport system, wherein the glass transport system comprises a metal vessel configured to convey molten glass, a support structure at least partially surrounding the metal vessel, and a thermal insulation material surrounding the support structure, the method comprising:
Conveying molten glass into the metal vessel A detection step to determine if there is molten glass leaking from the metal vessel injecting a silica-containing material inside at least one of the support structure or the thermal insulation material of the glass transport system, when a leak of the molten glass out of the metal vessel is detected, whereby the silica in the silica-containing material interacts with the molten glass to increase viscosity of the molten glass to mitigate or stop the glass leak.

2 . The method of claim 1 , wherein the silica-containing material comprises one or more of fused silica, quartz, cristobalite, high silica clay, non-oxide ceramics, oxide ceramics, or combinations thereof.

3 . The method of claim 1 , wherein the silica-containing material is in a paste form.

4 . The method of claim 1 , wherein the silica-containing material is injected into the support structure.

5 . The method of claim 1 , wherein the silica-containing material is injected into the thermal insulation material.

6 . The method of claim 1 , wherein the silica-containing material is injected into both the support structure and the thermal insulation material.

7 . The method of claim 1 , wherein injecting the silica-containing material comprises injecting the silica-containing material through one or more injection tubes extending into at least one of the support structure or the thermal insulation material.

8 . The method of claim 1 , detecting the leak of the molten glass out of the metal vessel.

9 . The method of claim 1 , wherein the metal vessel is a platinum or platinum allow metal vessel configured to convey molten glass at temperatures exceeding 1400° C.

10 . A glass transport system comprising:
a metal vessel configured to convey molten glass; a support structure comprising a refractory material at least partially surrounding the metal vessel; a thermal insulation material surrounding the support structure; and a silica-containing material injection system configured to, when the molten glass leaks out of the metal vessel, inject a silica-containing material inside at least one of the support structure or the thermal insulation material, whereby the silica in the silica-containing material interacts with the molten glass to increase viscosity of the molten glass to mitigate or stop the glass leak.

11 . The glass transport system of claim 10 , wherein the silica-containing material comprises one or more of fused silica, quartz, cristobalite, high silica clay, non-oxide ceramics, oxide ceramics, or combinations thereof.

12 . The glass transport system of claim 10 , wherein the silica-containing material is in a paste form.

13 . The glass transport system of claim 10 , wherein the silica-containing material is injected into both the support structure and the thermal insulation material.

14 . The glass transport system of claim 10 , wherein the silica-containing material injection system comprises one or more injection tubes extending into at least one of the support structure or the thermal insulation material.

15 . The glass transport system of claim 10 , further comprising a silica-containing material layer at least partially surrounding the support structure.

16 . The glass transport system of claim 10 , wherein the metal vessel comprises platinum.

17 . The glass transport system of claim 10 , wherein the support structure comprises a cradle configured to support the metal vessel.

18 . The glass transport system of claim 10 , wherein the refractory material comprises zirconia or alumina.

19 . The glass transport system of claim 18 , wherein the zirconia comprises fused zirconia.
