Abstract

Procedimiento para la producción de hierro bruto con ayuda de combustibles fósiles y regenerativos, en especial hulla y lignito, u otros combustibles orgánicos, como basuras y lodos de clarificación, a partir de minerales de hierro o de otros óxidos de hierro, que se suministran en su forma natural o preparados, como por ejemplo como productos sinterizados, productos aglomerados en bolas, mineral fino o concentrado, en un proceso de alto horno con una gasificación externa de los combustibles, caracterizado porque: al realizarse la gasificación en una primera etapa del proceso, se gasifica en forma química exotérmica para obtener gas de reducción una parte de los combustibles con aire y/o con oxígeno, añadiendo gas del tragante procedente del proceso del alto horno y/o vapor de agua, a una presión que es mayor que la presión existente en el alto horno a la altura de las toberas de viento y a una temperatura de entre 1.000 C y 1.800 C; en una segunda etapa del proceso de gasificación se introducen por soplado otros combustibles en el gas de reducción a alta temperatura procedente de la primera etapa del proceso, éstos reaccionan allí parcialmente en forma química endotérmica con el gas de reducción y la relación molar de los componentes reductores del gas, monóxido de carbono e hidrógeno, respecto a la relación de los componentes oxidantes, dióxido de carbono y vapor de agua, es por lo menos de 3 : 1 ; y el gas de reducción procedente de la segunda etapa de gasificación es introducido por soplado enelalto hornoala altura delastoberas de viento a una temperatura de entre 300 C y 1.000 C.
