  • Method for gas lancing
    Patent number: 4927357
    Abstract: A gas-injection lance, burner, and method for use in a high temperature heating system which provides a non-axisymmetric flow of a reaction-rate enhancing gas in sufficient proximity to the flame of the system, which extends over the surface to be heated, to create an aerodynamically reduced pressure field sufficient to deform the flame and displace it in the direction of the surface to be heated. The present method provides substantially enhanced heating with the virtual elimination of hot spots.
    Type: Grant
    Filed: October 12, 1989
    Date of Patent: May 22, 1990
    Assignee: The BOC Group, Inc.
