发明名称 DISPOSITIVO PARA A FUSAO DE MATERIAS VITRIFICAVEIS
摘要 <p>A vitrifiable material melting furnace has a glass melting and refining compartment discharging, at the downstream end, into a succession of compartments for passing the molten glass to the forming zone, the melting and refining compartment having a convective flow control device in the form of a transverse sill (14) which delimits the upstream and downstream zones. The sill is associated with a complementary upstream convective flow control system including an immersed heating system (15), located near and upstream of the sill, to prevent molten glass return from the downstream to the upstream zone. Also claimed is a process for operating the above furnace.</p>
