Abstract

La presente solicitud se refiere a un método y un aparato para producir DRI (Hierro de Reducción Directa) mediante el uso de un gas reductor de alta oxidación que contiene monóxido de carbono e hidrógeno, derivado en forma directa o indirecta de la gasificación de hidrocarburos o carbón, con un alto contenido de oxidantes (H2O y CO2). La solicitud provee un método más eficiente y una planta que comprende un reactor en el que un material de mineral de hierro en partículas toma contacto con un gas reductor de alta temperatura para producir DRI, con una menor inversión y menores costos de operación, con lo cual se evita la necesidad de un calentador a fuego para el gas reductor alimentado al reactor de reducción. El gas de reducción se calienta hasta una temperatura superior a 700ºC en dos pasos, un primer paso a una temperatura inferior a aproximadamente 400ºC para evitar el fenómeno de pulverización de metal (“metal dusting”), mediante el intercambio de calor sensible provisto por la corriente de gas caliente agotado retirada del reactor de reducción; y un segundo paso por medio de la combustión parcial o total con oxígeno, manteniendo la temperatura del gas de combustión por debajo de los límites establecidos por los materiales de construcción de la cámara de combustión.
