Air bubbler to increase glass production rate

Abstract

In a glass melter, a precious metal insert is used to protect a gas bubbler from corrosion at the orifice of the bubbler through which gas is injected into the melt. The use of a precious refractory metal insert at the bubbler orifice prevents the attack of molten glass on the bubbler. The precious metal is chosen from the refractory group of metals and the platinum group of metals. Preferably the precious metal from the platinum group is platinum or one of its alloys or one of ruthenium, rhodium, palladium, osmium and iridium. The precious metal from the refractory group is preferably chromium.
