METHOD OF AFTERBURNING OF COMBUSTIBLE GASES IN WORKING SPACE OF STEEL MELTING UNITS AND DEVICE FOR ITS EMBODIMENT

摘要

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).
