Abstract

LA INVENCION DESCRIBE UNA PARRILLA DE FLUIDIFICACION (13) PARA UN APARATO DE LECHO FLUIDO, QUE COMPRENDE DIVERSAS PROTUBERANCIAS O DIENTES (27), CADA UNO CON AL MENOS UN ORIFICIO DE PASO DE FLUJO GASEOSO (29, 31) DEFINIDO EN SU INTERIOR. LAS PARRILLAS DE FLUIDIFICACION CONVENCIONALES TIENEN ORIFICIOS DE TIPO ALETA QUE PRODUCEN INEVITABLEMENTE PEQUEÑAS FISURAS O RANURAS FORMADOS EN LA PORCION DEL BORDE QUE DEFINE CADA UNO DE LOS ORIFICIOS DE FLUJO. SEGUN LA INVENCION, LOS ORIFICIOS DE FLUJO DE GAS (29, 31) SE FORMAN EN LAS PROTUBERANCIAS O DIENTES (27) DE FORMA QUE SE EVITA LA FORMACION DE DICHAS RANURAS EN LA ZONA DEL BORDE. ESTO SE PUEDE LOGRAR, POR EJEMPLO, FORMANDO DICHOS ORIFICIOS CON BORDES EXENTOS DE FISURAS ANTES DE O TRAS LA FORMACION DE LAS PROTUBERANCIAS O DIENTES (29, 31). PARA ELLO, LOS ORIFICIOS SE PUEDEN FORMAR MEDIANTE PUNZONADO, PERFORACION, CORTE POR LASER O SIMILARES. CADA UNO DE LOS ORIFICIOS DE FLUJO DE GAS SE DIRIGE EN RELACION CON EL PLANO DE LA PARRILLA DE FLUIDIFICACION, A FIN DE PRODUCIR UN FLUJO DE GAS QUE ES CONDUCIDO A TRAVES DEL ORIFICIO, PARA ENTRAR EN CONTACTO CON UNA PARTE ADYACENTE DE LA PARRILLA DE FLUIDIFICACION, QUE INTERCONECTA LAS PROTUBERANCIAS O DIENTES (29, 31).
