Abstract
La invencion se refiere a un procedimiento y a una instalacion para la reduccion directa de minerales de hierro con un amplio espectro de distribucionde tamano de partícula por medio de hidrogeno como medio reductor en un canal de lechofluidific ado horizontal. Al canal de lecho fluidificado le precede unprecalentador [11], en el que es precalentado el mineral de hierro con ayuda de un así llamado top-gas proveniente del canal de lecho fluidificado horizontal.En un ciclon de gascaliente [13 ], emplazado a continuacion del precalentador [11], se separa del gas proveniente del precalentador [11] el mineral de hierroconteniendo en el mismo y es bajado a continuacion a la primera cámara [2] del canal de lecho fluidificadohorizontal. El m ineral de hierro a reducir esconducido a la primera cámara mediante la ayuda de recipientes presurizados [1]. En la primera y otras cámaras [2] están sumergidos intercambiadores de calor[4], los que calientan el mineral de hierro.Para el calentamien to del/de los intercambiadores de calor [4] se emplea un gas reductor altamente calentado, quees conducido a continuacion, como medio circulante y reductor, a los pisos de circulacion de las cámaras [2]. La velocidad defluidificacion en los pisos deirculacion de las cámaras [2] se ajusta mediante un dispositivo [5], de modo que permanezca y se reduzca un rango de tamano de partícula bien determinado encada cámara [2], y la fraccion con un tamano de partícula máspequeno de cada cámara [2] se descarga en un ciclon de cámara de gas caliente [6] y se separa engas y solidos de mineral de hierro. El mineral de hierro descargado correspondiente a cada ciclon [6] accede a la subsiguiente cámara. El gas de todoslosciclones de cámara de gas c aliente [6] es conducido,mediante una linea colectora [9], al precalentador [11]. El mineral de hierro separado en el ultimo ciclon
