Oxy Fuel Burner Manifold
Oxy-Gas
400 Series Title

    Features

    • High heat input

    • High turndown ratio

    • Concentrated sidewall heating

    • Low volume of combustion Products and reduced volatilisation

    • Integrated safety features
    		Benefits

    • Improved thermal Homogeneity

    • Faster responses

    • Increased glass throughput

    • Improved glass quality

    • Longer superstructure refractory life with volatile glasses

    The BH-F/BOC Oxy-gas forehearth has now been proven for high temperature applications

    The forehearth was developed by BH-F (Engineering) Ltd and BOC Gases with the assistance of Corning Incorporated.
    It has been designed to provide highly controllable heating of the side glass in a forehearth
    Without the high levels of combustion products that affect centre glass temperatures and internal forehearth pressure.
    The result is a more responsive forehearth that delivers higher throughput, better thermal homogeneity and improved glass quality with less refractory damage.
