GLASS-FURNISHED OVEN FOR THE PRODUCTION OF COLORLESS OR SUPERBESCOLORED GLASS WITH SECONDARY SIDE VORTEXES OF RECIRCULATION

摘要

Glass melting furnace for heating and melting glass-forming substances, in which two loops of molten glass are formed in the bath between the hotter central zone of the furnace and, respectively, the inlet (E) and the outlet (Y) with a lower temperature; the furnace contains side means (12a, 12b) to create or enhance lateral secondary vortices (B2La, B2Lb) of glass recirculation.
