Abstract

QUE CONSISTE EN CALCULAR LA CANTIDAD TOTAL DE OXIGENO EN EL GAS DE TOSTACION QUE SE VA A ALIMENTAR, Y EL PROMEDIO TOTAL DE REQUERIMIENTO DE OXIGENO DEL MATERIAL QUE SE VA A TOSTAR Y LA PROPORCION ENTRE AMBOS SE REGULA DE MODO QUE EL COEFICIENTE DE OXIGENO EN EL LECHO SEA MAYOR QUE 1. DICHO COEFICIENTE ES REGULADO POR CAMBIO DE TEMPERATURA, POR CAMBIO DE LA CANTIDAD DE GAS DE TOSTACION O POR CAMBIO DEL ENRIQUECIMIENTO DE OXIGENO DEL GAS TOSTADOR. PARA REGULAR DICHO COEFICIENTE SE TOMA, EN FORMA CONTINUA, DEL LECHO FLUIDIZADO LA MEDICION DEL CONTENIDO DE OXIGENO CUANDO SE CAMBIA LA MEZCLA DE ALIMENTACION. EL GAS DE TOSTACION ES AIRE O AIRE ENRIQUECIDO CON OXIGENO. EL MATERIAL A TOSTAR ES UN CONCENTRADO DE ZINC O UN CONCENTRADO DE SULFURO CONTENIENDO HIERRO
