Molten glass has a liquid level located at a higher level than lower ends of an uprising pipe and a downfalling. In addition, a contacting portion of the uprising pipe or the downfalling pipe and a brick receiver on an upstream or downstream pit for supporting the uprising or downfalling pipe, or a joint in the brick receiver is filled with sealing material.

Vacuum degassing apparatus for molten glass

A vacuum degassing apparatus comprises a path made of dense refractory bricks, the path including an inner surface brick layer, the refractory bricks in the inner surface brick layer having a flatness of 0.5 mm on contacting surfaces with one anther, and the path including a backup brick layer and a ramming material filling layer besides the inner surface brick layer.

Vacuum degassing apparatus for molten glass and method for building it

The present invention provides a vacuum degassing system,having a leakage valve,installed between a condenser,and a vacuum pump,wherein even when the leakage valve,is opened, a vacuum degassing vessel,is not released to the atmosphere to thereby constantly maintain a temperature in the vacuum degassing vessel,and a large amount of volatile matters in the vacuum degassing vessel,are not discharged to a gas release pipe,whereby the vacuum degassing vessel,can be stably operated.

Vacuum gas releasing system

Before operating a vacuum degassing apparatus for molten glass which has paths for molten glass made of refractory material, fuel is burned by temperature rising burners, and the burned gas is exhausted through an exhaust pipe which communicates to an upper end of a vacuum degassing vessel.
