ABSTRACT:
A burner tip for passing fuel into a glass melting chamber, the burner tip having at least a portion thereof extending a distance into a fuel input passageway fluidly communicating the chamber interior to the chamber exterior, the distance being sufficient to minimize inspiration of chamber exterior or ambient air through an unsealed space formed between the outside surface of the burner tip and the walls forming the fuel input passageway, into the chamber interior, wherein at least the portion of the burner tip which extends into the fuel input passageway is made of high temperature, high oxidation-resistant material capable of withstanding the chamber interior atmosphere during both firing and off-firing cycles, while in direct contact therewith over a substantial time period. The input passageway-extending portion of the burner tip can be precoated with an inhibitor coating to minimize resistant material volitilization and to minimize reactions between the resistant material and refractory materials, especially refractory cement which may be employed to seal the unsealed space.
