Abstract

PROCEDIMIENTO PARA LA REDUCCION DIRECTA DE MATERIALES QUE CONTENGAN OXIDO DE HIERRO. CONSISTE EN APORTAR ACEPTORES DE AZUFRE Y OTROS MATERIALES DE APORTACION, EN EL MISMO SENTIDO Y/O A CONTRACORRIENTE CON LOS GASES QUE FORMAN EL LECHO DE TURBULENCIA, DONDE EL GAS SUPERIOR PROCEDENTE DEL HORNO DE CUBA DE REDUCCION (18), Y CON UNA CONCENTRACION DE 15 A 30% CO2 Y A UNA TEMPERATURA DE 80 A 800JC SE RECONDUCE LATERALMENTE A TRAVES DE LA PARED DEL GENERADOR DE GAS (1) A LA ZONA DEL LECHO DE TURBULENCIA MANTENIDA A 1.150JC, DONDE LA TEMPERATURA DEL GENERADOR DE GAS (1), Y QUE CONTIENE CENIZAS Y COMBINACIONES DE AZUFRE, Y QUE SE VA ACUMULANDO FORMANDO UN BAÑO (12) SE ELIMINA A TRAVES DE UNA SANGRIA (13).
