  • Auxiliary oxygen burners technique in glass melting cross-fired regenerative furnaces
    Patent number: 5147438
    Abstract: The invention relates to the employment of at least one oxygen-fuel burner in a particular manner in glass melting cross-fired regenerative furnaces. By operating oxygen-fuel burners positioned in particular places in a cross-fired regenerative furnace in an appropriate manner, the glass melting can be accomplished without disrupting the flame momentum of the air-fuel burners, thereby improvidng the efficiency of the glass melting and increasing the production of the glass products.
