Abstract
Se describe un proceso para reducir el óxido de hierro a hierro metálico utilizando gas de horno de coque (COG), que incluye: un horno de cuba de reducción directa para proporcionar un gas de escape; una fuente de COG para inyectar COG dentro de una corriente de gas reductor que incluye al menos una porción del gas de escape; y el horno de cuba de reducción directa que reduce el óxido de hierro a hierro metálico utilizando la corriente de gas reductor y el COG inyectado. El COG tiene una temperatura de aproximadamente 1,200 grados C o mayor después de la inyección. El COG tiene un contenido de CH4 de entre aproximadamente 2% y aproximadamente 13%. Preferentemente, el COG es COG reformado. Opcionalmente, el COG es COG caliente fresco. La fuente de CDG incluye un sistema de oxidación parcial. Opcionalmente, la fuente de COG incluye un quemador de oxígeno caliente.
