Water cooled oxygen lance for use in a float glass furnace and/or float glass furnace using the same

摘要

A float glass furnace includes a melting furnace which heats raw materials to form a molten glass batch, a working end where the molten glass batch is cooled, at least one regenerator which introduces heated combustion air into the melting furnace through a port neck, and at least one oxygen lance in or proximate the port neck. The oxygen lance includes a lance pipe in fluid communication with the port neck, an outer shell surrounding the lance pipe, an inlet water passageway in fluid communication with a channel(s) between an exterior surface of the lance pipe and an interior surface of the outer shell, and an outlet water passageway in fluid communication with the channel(s).
