摘要： According to the process, a mixture of powdered mineral substances is introduced at one end of a furnace and this mixture is heated, and the molten glass thus obtained is continuously discharged at the other end of the furnace. The mixture is heated by means of at least one air-fuel flame and at least one oxygen-fuel flame. A current of auxiliary gas which is concentric to and surrounds the oxygen-fuel flame is injected into the furnace.

摘要： 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).

摘要： A process and installation for heating a channel in which flows a mass of molten glass toward one or more forming machines. The channel includes a vault which carries at least one group of oxyfuel burners connected to a source of oxygen and to a source of fuel gas, these burners being so oriented as to produce curtains of flames directed towards the longitudinal marginal zones of the surface of the stream of molten glass.
