Abstract

LA PRESENTE INVENCION SE REFIERE A UN METODO PARA LA FABRICACION DE HORNO DE LECHO FLUIDIFICADO CON CIRCULACION EXTERNA QUE NO NECESITA LA PRESENCIA DE UN CAMARA PARA RETENER AL MEDIO DE TRANSPORTE DE CALOR EN COMUNICACION CON EL CONDUCTO DE TUBO DESCENDENTE. SEGUN EL METODO DE LA PRESENTE INVENCION, DICHA CAMARA SE ELIMINA A BASE DE DETERMINAR DE MANERA CORRECTA LA DIMENSION DEL CONDUCTO DE TUBO DESCENDENTE, ETC. SEGUN LA PRESENTE INVENCION, LA RELACION ENTRE EL DIAMETRO DEL CONDUCTO DE TUBO DESCENDENTE CON EL DIAMETRO DEL TUBO ASCENDENTE RESPECTO A ESA RELACION (X) ENTRE LOS MISMOS SE ENCUENTRE EN UN AREA ENTRE DOS LINEAS DESCRITAS COMO SIGUE, EN UN PLANO WS-X: WS=12500X5-12080X4+4370X3-600X2+36X Y WS=5800X4+1600X3-580X2+44X EN DONDE WS ES LA VELOCIDAD DE CIRCULACION DEL MEDIO DE TRANSPORTE DE CALOR SOLIDO EN EL TUBO ASCENDENTE POR CADA UNIDAD DE SUPERFICIE DE SECCION TRANSVERSAL (KG/M2SEG); X ES UNA RELACION DEL DIAMETRO DEL CONDUCTO DE TUBO DESCENDENTE (D) RESPECTO AL DIAMETRO DEL TUBOASCENDENTE (D).
