Abstract

UN SISTEMA PARA LA PRODUCCION DIRECTA DE HIERRO REDUCIDO EN EL QUE EL MATERIAL DE OXIDO DE HIERRO Y EL MATERIAL DE CARBONO SE HACE PASAR SUCESIVAMENTE A TRAVES DE UNA ZONA DE OXIDACION Y UNA ZONA DE REDUCCION DE UN HORNO, ESTANDO CADA ZONA ALIMENTADA CON FUEGO POR COMBUSTION DE COMBUSTIBLE OXIGENADO, QUE PERMITE UNA REDUCCION EN LA CANTIDAD DEL COMBUSTIBLE NECESITADO PARA PROCESAR EL MATERIAL A LA VEZ QUE SE GENERA EL SUFICIENTE MONOXIDO DE CARBONO PARA EFECTUAR LA REDUCCION Y ASEGURAR QUE EL HORNO EMITE POCA CANTIDAD O NINGUNA CANTIDAD DE MONOXIDO DE CARBONO.
