ABSTRACT:
An improved method for the production of steel which results in reducing the volume of off-flow gases which are created in the production of steel by the Basic Oxygen Steel Process. The method involves introduction of oxygen within the flame cone of the off-flow gases, above the opening of the furnace, resulting in oxidation of carbon monoxide to carbon dioxide. Turbulence of the off-flow gases is created through the further introduction of steam or air into the flame cone of the off-flow gases, which results in improvement of the rate of oxidation of the carbon monoxide.
