Abstract
Abstract A burning tip for an industrial gas cutting torch comprising an elongated hollow outer shell element having an insert mounted therein. The lower end of the insert terminates inside and spaced from the lower end of the hollow shell element to provide a compartment therein. The lower end of the outer shell element is provided with an inwardly extending annular shoulder which creates interference for the combustible gases so that gas turbulence is created within the compartment to enhance the oxygen-gas mixture therein to improve combustion. The configuration of the shoulder and its relationship to the compartment results in a mushroom-shaped preheating flame.
