FOREHEARTH HEATING

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.
