  • Roof-mounted oxygen-fuel burner for a glass melting furnace and process of using the oxygen-fuel burner
    Patent number: 6237369
    Abstract: Briefly, according to the present invention there is provided a refractory lined glass melter for producing refined glass from raw glass-forming material using at least one oxygen-fuel burner recessed within a burner block mounted in the roof of the furnace and a process of using the burner. The velocities of the gaseous fuel and of the oxygen from the oxygen-fuel burner are controlled such that the velocities of the gaseous fuel and the oxygen are substantially equivalent to provide a generally laminar gaseous fuel and oxygen flow to combust proximate a top surface of the raw glass-forming material and produce a flame which impinges the surface of the raw glass-forming material and which has a middle portion of a columnar shape.
