Abstract

Provided is a glass product manufacturing apparatus. The glass product manufacturing apparatus includes a furnace including a gas heating zone and an electric heating zone, a first heat exchange module configured to recover heat from the furnace, and a pump configured to drive flow of a heat transfer medium fluid passing through the first heat exchange module, wherein at least a part of the first heat exchange module is thermally coupled with at least a part of an external surface of the electric heating zone. The glass product manufacturing apparatus may reduce defect rate while exhibiting high energy efficiency.

First claim

What is claimed is:

1. A glass product manufacturing apparatus comprising:
a furnace comprising a gas heating zone and an electric heating zone;
a first heat exchange module configured to recover heat from the furnace; and
a pump configured to drive flow of a heat transfer medium fluid passing through the first heat exchange module,
wherein at least a part of the first heat exchange module is thermally coupled with at least a part of an external surface of the electric heating zone.

2. The glass product manufacturing apparatus of claim 1 , further comprising:
a glass product processor configured to supply a processing fluid for processing the glass product; and
a second heat exchange module configured to heat the processing fluid,
wherein the second heat exchange module is configured to transfer heat from the heat transfer medium fluid to the processing fluid.

3. The glass product manufacturing apparatus of claim 1 , wherein the gas heating zone is at a higher level than a highest level of glass melt in the furnace, and the electric heating zone is at a lower level than the highest level of the glass melt in the furnace.

4. The glass product manufacturing apparatus of claim 3 , wherein at least a part of the first heat exchange module is in surface contact with an external surface of the electric heating zone.

5. The glass product manufacturing apparatus of claim 4 , wherein the first heat exchange module is adhered to the external surface of the electric heating zone via a fixing member.

6. The glass product manufacturing apparatus of claim 4 , wherein a surface-contact area between the first heat exchange module and the external surface of the electric heating zone ranges from about 15% to about 60% of an entire area of an external wall on which the first heat exchange module is provided.

7. The glass product manufacturing apparatus of claim 1 , wherein the first heat exchange module is spaced apart from the external surface of the furnace.

8. The glass product manufacturing apparatus of claim 7 , wherein a surface of the first heat exchange module facing the external surface of the furnace is substantially parallel with the external surface of the furnace.

9. A glass product manufacturing apparatus comprising:
a furnace comprising a gas heating zone and an electric heating zone;
a glass product processor configured to supply a processing fluid for processing the glass products; and
a heat exchange device,
wherein the heat exchange device comprises:
a first heat exchange module configured to recover heat from the furnace;
a second heat exchange module configured to heat the processing fluid;
a heat transfer medium fluid circulating between the first heat exchange module and the second heat exchange module; and
a pump configured to drive a flow of the heat transfer medium fluid, wherein the heat transfer medium fluid is water.

10. The glass product manufacturing apparatus of claim 9 , wherein the first heat exchange module comprises three sections spaced apart from one another in a lateral direction.

11. The glass product manufacturing apparatus of claim 9 , wherein the first heat exchange module is configured to raise a temperature of the heat transfer medium fluid by about 7° C. to about 15° C.

12. The glass product manufacturing apparatus of claim 11 , wherein the second heat exchange module is configured to raise a temperature of the processing fluid by about 3° C. to about 8° C.

13. The glass product manufacturing apparatus of claim 9 , further comprising a first tank configured to store the heat transfer medium fluid supplied to the first heat exchange module, wherein the heat transfer medium fluid discharged from the first heat exchange module is configured to recycle to the first tank.

14. The glass product manufacturing apparatus of claim 13 , further comprising a second tank configured to store the heat transfer medium fluid discharged from the second heat exchange module.

15. The glass product manufacturing apparatus of claim 9 , wherein the furnace comprises a first side wall to which a supply device for supplying a raw material is coupled and a second side wall in which a glass melt outlet is mounted, and the first heat exchange module directly contacts the first side wall.
