Abstract
A glass fining system, glass fining device, and method are disclosed. The glass fining device in accordance with one aspect of the disclosure includes at least one heated orifice through which molten glass flows from a glass melter to produce at least one superheated glass stream; and a low-pressure chamber disposed downstream from the heated orifice, where the at least one superheated glass stream flows from the at least one heated orifice and into the low-pressure chamber, and where the low-pressure chamber surrounds the at least one superheated glass stream. In some embodiments, the low-pressure chamber may include at least one surface extender.
Claims23
A glass fining device, comprising:
- at least one heated orifice device including at least one orifice through which molten glass flows from a glass melter to produce at least one superheated glass stream;
- and
- a low-pressure chamber disposed downstream from the heated orifice device, where the at least one superheated glass stream flows from the at least one heated orifice device and into the low-pressure chamber, and where the low-pressure chamber surrounds the at least one superheated glass stream.
A glass fining system, comprising:
- a glass melter;
- and
- a glass fining device coupled to the glass melter, including
- at least one heated orifice device through which at least one superheated glass stream flows from the glass melter,
- a low-pressure chamber disposed downstream from the at least one heated orifice device, where the at least one superheated glass stream flows from the at least one heated orifice device and into the low-pressure chamber, and where the low-pressure chamber surrounds the at least one superheated glass stream.
A method for fining molten glass, comprising:
- melting glass in a glass melter,
- flowing the molten glass from the glass melter through at least one heated orifice device resulting in a superheated glass stream;
- and
- flowing the at least one superheated glass stream from the at least one heated orifice device into a low-pressure chamber, where the low-pressure chamber surrounds the at least one superheated glass stream.
