Title:
METHOD AND APPARATUS FOR REDUCING CONDENSATE RELATED DEFECTS IN A GLASS MANUFACTURING PROCESS
Document Type and Number:
WIPO Patent Application WO/2011/066248
Kind Code:
A3
Abstract:
The present invention is directed toward an apparatus and method of reducing contamination of a glass melt by oxide particulates, such as particulates of platinum oxide, which may condense on the inside surfaces of a stir chamber, particularly the stir shaft, and fall back into the glass melt. The apparatus includes a condensation collection vessel arranged annularly around the stir shaft of a stirring device. The collection vessel is located above the free surface of the molten glass occupying the stir chamber and serves to collect any condensed particulates that have formed on the stir chamber cover or gaps within the cover itself. By collecting the condensate, defects in the final glass product that would otherwise be created by the condensate, can be avoided. A method of stirring a glass melt is also provided.
