Abstract

Un sistema de alto horno en el que el consumo de coque se disminuye recirculando gas efluente del alto horno regenerado al mismo alto horno en su sección de cuba, y donde dicho gas efluente regenerado es calentado en un calentador tubular antes de ser recirculado. El gas efluente que comprende CO, CO2, y H2, se extrae de la parte superior del alto horno, se enfría y limpia de polvo, y se separa agua y CO2 del mismo para aumentar su potencial reductor y es calentado a una temperatura superior 850 c antes de ser recirculado al alto horno, definiendo a si una primera ruta de circulación de gas que se utiliza durante la operación normal del alto horno. Una segunda ruta de circulación de gas se usa para circular de manera continua gas efluente, selectivamente a través del calentador y un enfriador, durante las interrupciones de operación del alto horno, lo cual da tiempo para realizar un enfriamiento gradual y controlado del calentador, de manera que se evitan daños a dicho calentador por choques térmicos.
