Abstract

LA ESPECIFICACION MUESTRA UN PROCESO PARA PRE-CALENTAR Y PRE-REDUCIR MINERALES DE OXIDO METALICOS. EL PROCESO COMPRENDE LA INTRODUCCION DE PARTICULAS DE MINERAL DE OXIDO OBTENIDAS EN UN GAS A TRAVES DE UNA PUERTA EN UNA CAMARA DE TRATAMIENTO. DENTRO DE LA CAMARA DE TRATAMIENTO LA CORRIENTE DE PARTICULAS EN TREN SE COMBINA CON UNA CORRIENTE DE GAS REDUCTOR DE ALTA TEMPERATURA DE MANERA TAL QUE LAS PARTICULAS SE CALIENTAN RAPIDAMENTE Y ENTRAN EN PATRONES DE FLUJO EN LOS QUE ENTRAN EN CONTACTO CON OTRAS PARTICULAS Y LA SUPERFICIE INTERNA DE LA CAMARA DE TRATAMIENTO SE MINIMIZA. LA CORRIENTE DE PARTICULAS EN TREN EN LA CORRIENTE DE GAS REDUCTOR DE ALTA TEMPERATURA SON SUBSTANCIALMENTE CO-CORRIENTE. SE DESCRIBE EN LA ESPECIFICACION UNA CAMARA DE TRATAMIENTO ELONGADA EN LA DIRECCION DEL FLUJO CO-CORRIENTE. LOS GASES DE RESIDUOS CALIENTES SE PUEDEN DERIVAR DESDE UN REACTOR DE BAÑO FUNDIDO Y CONSTAN DE UNA ALTA CONCENTRACION DE HIDROGENO Y MONOXIDO DE CARBONO.
