Method and apparatus for post-combustion (after-burning) of the combustible gases present in a metallurgical vessel used for smelting metals. A swirling flow of an oxidizing gas emanating from a radiant injector (10) having a funnel-shaped (conical) diffuser (14) causes a reaction between the combustible gases and the oxidizing gas at the inner surface (13) of the diffuser (14) thereby further heating the inner surface (13). Heat from the inner surface (13) of the diffuser (14) is radiated inside the vessel toward the metal (12). Fuel gas can be supplied to the radiant injector to aid in heating of the inner surface (13) of the diffuser (14).
L'invention concerne un procédé et un appareil permettant la combustion des gaz combustibles présents dans un four métallurgique utilisé pour fondre des métaux. Un flux tourbillonnaire de gaz oxydant sortant d'un injecteur rayonnant (10) ayant un diffuseur (14) en forme d'entonnoir (conique) entre en réaction avec les gaz combustibles au niveau de la surface interne (13) du diffuseur (14), ce qui a pour effet de chauffer cette surface. La chaleur produite sur la surface interne (13) du diffuseur (14) se répand à l'intérieur du four en direction du métal (12). On peut alimenter l'injecteur rayonnant avec un gaz combustible pour chauffer davantage la surface interne (13) du diffuseur (14).
