摘要： Disclosed is a parallel arrangement of vacuum degassing apparatus (100) comprising: a plurality of vacuum degassing units (102,104) for vacuum-degassing molten glass (G) supplied from a melting vessel; wherein each of the vacuum degassing units (102,104) includes a vacuum housing (13;14) where a vacuum is created, a vacuum degassing vessel (14;15) housed in the vacuum housing (12;13) to vacuum-degas the molten glass (G), an introduction device (16;52) communicated to the vacuum degassing vessel (14;15) so as to introduce the molten glass (G) before degassing into the vacuum degassing vessel (14;15); and a discharge device (18;19;54) communicated to the vacuum degassing vessel (14;15) so as to discharge the molten glass (G) after degassing from the vacuum degassing vessel (14;15). A pressure equalising pipe (142) is provided to communicate between the vacuum degassing units (102,104), and a merging unit (150) for merging the molten glass (G) supplied from the vacuum degassing unit (102,104), stirring the merged molten glass (G) and supplying the stirred molten glass (G) to a downstream side.
