Abstract
Device for improving the heating of a channel (2) for distribution of glass (1), said device including a cylindrical duct (6) connected at its upstream end to means (7) for feeding a premixture of air and fuel gas and whose downstream end (8) opens inside a cylindrical bore (9) in a refractory block (10) inserted in a wall (11) of the channel, said cylindrical bore (9) extending by means of a coaxial cylindrical duct (12), of smaller diameter than that of said bore, the cylindrical channel (6) being surrounded by a sealing ring (13) which covers the face of the cylindrical bore (9) in which said channel (6) is inserted. According to the invention, the device comprises a capillary tube (20) coaxially disposed with respect to said duct (6) and whose diameter is smaller than the diameter of said duct (6), said capillary tube (20) being connected at its upstream end to oxygen feeding means (21) opening at the downstream end (8) of said duct (6) between the end (22) of the coaxial cylindrical duct located toward said channel and the downstream end (8) of said duct (6).
