Abstract

A method and system that uses a cold wall furnace for melting the materials that are feed into the furnace. In one aspect, at least a portion of the exterior surface of the cold wall furnace is surrounded by at least one jacket configured to transfer heat away from the metal liner of the furnace. This cooling causes the molten glass to solidify on the metal surface of the metal liner of the cold wall furnace, which acts to protect the metal liner of the furnace from oxidation during molten glass evacuation and subsequent exposure to atmosphere.

Claims

1. A modular glass melter, comprising:

a furnace defining an interior volume;

a means for heating the interior volume;

a jacket surrounding at least a portion of an exterior surface of the furnace, wherein the jacket defines an interior cavity, and wherein the internal cavity is at least partially filled with a thermally conductive fluid; and

a valve in communication with the interior volume of the furnace configured to regulate the flow of molten glass out of the interior volume of the furnace.

2. The modular glass melter of claim 1, wherein the furnace is substantially positioned within a furnace casing.

3. The modular glass melter of claim 2, wherein the furnace casing comprises Molybdenum.

4. The modular glass melter of claim 2, wherein the furnace casing comprises Copper.

5. The modular glass melter of claim 2, wherein the furnace casing comprises Methylsilazane.

6. The modular melter of claim 1, further comprising a closed loop feedback system configured to control the valve.

7. The modular melter of claim 6, wherein the valve comprises a precious metal.

8. The modular melter of claim 7, wherein the precious metal comprises Platinum.

9. The modular melter of claim 1, wherein the valve defines an interior passageway, and wherein the valve comprises a means for heating the interior passageway.

10. The modular melter of claim 7, wherein the valve is mounted thereto a bottom portion of the furnace.

11. The modular melter of claim 1, wherein the thermally conductive fluid comprises a glycol and water mixture.

12. A system for making glass, comprising:

a plurality of modular melters, each modular melter comprising;

a furnace defining an interior volume;

a means for heating the interior volume;

a jacket surrounding at least a portion of an exterior surface of the furnace, wherein the jacket defines an interior cavity, and wherein the internal cavity is at least partially filled with a thermally conductive fluid; and

a valve in communication with the interior volume of the furnace configured to regulate the flow of molten glass out of the interior volume of the furnace.

a glass refiner in fluid communication with each of the modular melters; and

a plurality of glass feeders in fluid communication with the glass refiner.
