Abstract

La presente invención se refiere a un método y un aparato para producir DRI (Hierro Reducido Directo) que utiliza un gas de reducción de oxidación alta que contiene monóxido de carbono e hidrogeno, entregado directa o indirectamente de la gasificación de hidrocarburos o carbón con un alto contenido de oxidantes (H2O y CO2) La invención proporciona un método mas eficiente y una planta que comprende un reactor en la cual el material particulado de mineral de hierro entra en contacto con un gas de reducción de alta temperatura para producir DRI, con costos de inversión inferiores y de operación, evitando la necesidad de un calentador a fuego para el gas de reducción alimentado en el reactor de reducción. El gas de reducción se calienta a una temperatura arriba de 700° C en dos pasos, un primer paso a una temperatura inferior aproximadamente a 400°C para prevenir el fenómeno de pulverización metálica, mediante el intercambio de calor sensible proporcionado por la corriente de gas gastado de calor removido del reactor de reducción y un segundo paso mediante la combustión parcial o total con oxigeno, manteniendo la temperatura del gas de combustión inferior a los limites establecidos por los materiales de construcción de la cámara de combustión.
