FORFARANDE OCH SMELTVANNA FOR FRAMSTELLNING AV GLAS

摘要

In a glass melting tank, a plurality of stirrers are spaced apart across the tank and arranged to extract heat from the forward flowing glass so as to achieve a differential extraction of heat from the glass which flows along a return path towards the inlet end after stirring, and that glass which continues along a forward path to the outlet end of the tank.
