Patent ID: 8448469

Claim:
An apparatus for manufacturing a float glass by floating the glass on a molten tin that is contained in a molten tin bath, the apparatus comprising: a molten tin bath; a discharge line that is connected to a downstream zone of the molten tin bath, and discharges a portion of the molten tin in the molten tin bath to the outside of the molten tin bath; a stripping chamber including an oxygen stripping chamber that is connected to the discharge line and receives the molten tin discharged from the molten tin bath through the discharge line and a heating chamber integrally combined with the stripping chamber, and the stripping chamber being spatially divided to form the oxygen stripping chamber and the heating chamber by a partition having a through hole to transfer the molten tin from which oxygen is removed in the oxygen stripping chamber into the heating chamber; a bubbling device including a porous plate that is provided in the oxygen stripping chamber and bubbles the oxygen stripping gas including hydrogen through the porous plate into the molten tin in the oxygen stripping chamber; and a returning line that returns the molten tin from which oxygen is removed by the bubbling device to an upstream of the molten tin bath.
