Abstract
An apparatus for refining molten glass that includes a housing having a vertically oriented longitudinal axis and a transverse axis perpendicular to the longitudinal axis. Molten glass is received at an upper end of the housing and is discharged from a lower end of the housing. A guide extends at least partway across the housing and directs molten glass in a generally downward direction through the housing and in a parallel or oblique direction relative to the transverse axis of the housing.
Claims20
An apparatus for refining molten glass that includes:
- a housing having a vertically oriented longitudinal axis, a transverse axis perpendicular to said longitudinal axis, a length measured along the longitudinal axis, and a width measured along the transverse axis, wherein the length is greater than the width, and a transverse cross-sectional area between 0.5 square meters and 20 square meters;
- an inlet at an upper end of said housing to receive unrefined molten glass;
- an outlet at a lower end of said housing to discharge refined molten glass from said housing;
- and
- a guide positioned within said housing having a flow surface upon which molten glass can flow between said inlet and said outlet of said housing, said flow surface having a surface area between 50 square meters and 500 square meters, such that the surface area of the flow surface is 2.5 to 1,000 times greater than the surface area of the transverse cross-sectional area of the housing.
