Abstract
La invención se refiere principalmente a un método de reciclaje del gas de alto horno en el cual al menos una parte del gas salido del alto horno se somete a una etapa de depuración del CO2 para crear un gas rico en CO que es reinyectado en un primer punto de inyección elevada situado arriba de la base del alto horno a una temperatura comprendida entre 700 y 1000 oC al nivel de una línea de inyección elevada, y en un segundo punto de inyección baja, con respecto a la base del alto horno a una temperatura comprendida entre 1000 °C y 1300 oC al nivel de una línea de inyección baja, en el cual los gases de las líneas de inyección baja y elevada son calentados por medio de recalentadores en los cuales el gas sale a una temperatura comprendida entre 1000 °C y 1300 °C. El procedimiento de la invención está caracterizado esencialmente porque una parte del gas rico en CO (18) a la salida de la etapa de depuración se introduce directamente en la línea de inyección elevada (21) por medio de una línea de inyección de gas enfriado (35) para obtener una temperatura comprendida entre 700 y 1000 °C en el primer punto de inyección elevada (20), y porque la regulación de los caudales del gas al nivel de los puntos de inyección baja (22) y elevada (20) se efectúa río arriba del sistema de recalentadores (30, 33; 45) La invención se refiere igualmente a un dispositivo que utiliza el procedimiento precitado.
