Document Type and Number:
WIPO Patent Application WO2002079107
Kind Code:
A3
Abstract:
The invention relates to a method and a device for producing and/or preparing molten glass. The invention is characterised by the following: the molten glass flows in a container (1) in a principal flow direction (A), the level of the molten glass being at a specific height above the base surface (1.6) of the container (1); streams of a free-flowing medium are introduced into the molten glass in such way that said glass flows in spiral paths and that the axes of the spirals run parallel or approximately parallel to the principal flow direction (A); neighbouring inlet points of the streams are separated by a mutual distance, (viewed from the principal flow direction (A)), of at least 0.5 times the height of the molten glass level.
