Abstract

Una comente caliente de oxígeno que contiene radicales es alimentada en una corriente de gases radioactivos de un envase hecho de acero para convertís monóxido de carbono en el gas radiactivo a dióxido de carbono. Un método para tratar una corriente de gas radioactivo de un horno de acero es proporcionado: (A) proporcionar una corriente de gas radioactivo que tiene una temperatura menor a 2000F obteniendo gas radioactivo del atmósfera debajo de la superficie del acero derretido en un horno, cuyo gas radioactivo obtenido contiene monóxido de carbono mayor a 500 ppm, admitiendo aire en el gas radioactivo obtenido y enfriando el gas radioactivo a la medida necesaria de manera que está a una temperatura de menos de 2000F: (B) mezclar combustible y oxígeno y combustionar una porción del oxígeno en la mezcla con el combustible en una cámara para formar una corriente do oxígeno caliente que sale de una salida en dicha cámara que contiene oxígeno, en donde el tiempo de residencia de la combustión en la cámara es demasiado largo de manera que la comente de oxígeno tiene una temperatura mayor a la comente de gas radioactivo a la cual se adiciona la etapa (C). (C) Alimentar la corriente de oxígeno caliente formado en la etapa (B).
