Assignee:

OCV Intellectual Capital LLC - DE

International Classification:

C03B 5/16

US Classification:

65346, 65347, 65335, 65179, 65355, 432247

Abstract:

A front end for a glass forming operation including an open channel and at least one burner. The channel surface has at least one burner port and a burner oriented in the burner port at an acute angle relative to the channel surface. The surface may be a top, side or end wall and the burner port is at an acute angle relative to the surface of the wall.

US Classification:

65335, 65337, 65346, 65347, 65135, 432195

Abstract:

A glass-melting furnace () has an upstream end (), a downstream end (), and a roof (). The upstream end is positioned upstream of the downstream end. A charger () is provided to supply glass-forming material () to the upstream end of the furnace. At least one burner () is provided to supply heat to the glass-forming material at the upstream end of the furnace. An exhaust () is in communication with the downstream end of the furnace, with the exhaust being positioned downstream of the at least one burner.

Abstract:

A front end for a glass forming operation comprises an open channel and at least one burner. The channel has at least one surface. The surface has at least one hole therein. The burner is oriented in the hole at an acute angle relative to the surface. In another embodiment of the invention, the channel has a top and a pair of sidewalls each having a surface. At least one hole is in at least one of the surfaces. The hole is at an acute angle relative to at least one surface. The burner is an oxygen-fired burner. In yet another embodiment of the invention, the top and sidewalls each have a super structure surface constructed of refractory material. The channel has an upstream end and a downstream end. At least one of the surfaces has a plurality of holes therein. The burners extend at an acute angle relative to at least one surface and in a plane extending between the upstream end and the downstream end and perpendicular to at least one surface.

International Classification:

C03B 37/085
C03B 37/00
C03B 7/06

US Classification:

65495, 65540

Abstract:

Forehearths that create a substantially homogeneous temperature to molten glass forming materials across the end position are provided. A gas cavity, a weir, a refractory block, or a heating element in the forehearth may be utilized to reduce a temperature gradient of molten glass forming materials across the end position. Reducing the temperature difference of the molten glass forming material across the end position permits for improved chemical and physical properties of the glass fibers and the end products formed from the glass fibers. In addition, a reduction in the temperature gradient across the end position produces a more homogenous glass fiber and glass product. Further, a reduction in the shear break rate occurs when the molten glass forming material has a temperature that is substantially the same across the end position, which results in a reduction in the breakage of glass fibers and an increase in manufacturing efficiency.
