Abstract

SE REFIERE A UN METODO PARA CONTROLAR EL NIVEL Y/O LA EXISTENCIA DE SOLIDOS EN UN TANQUE DE LECHO FLUIDIZADO, DEL CUAL UN FLUJO DE SOLIDOS ES RETIRADO VIA UNA TUBERIA DESCENDENTE; EN DONDE EL FLUJO DE SOLIDOS RETIRADO ES FLUIDIZADO EN LA PARTE INFERIOR DE LA TUBERIA DESCENDENTE MEDIANTE EL SUMINISTRO DE UN GAS TRANSPORTADOR Y ES TRANSPORTADO A UN NIVEL MAS ALTO VIA UNA TUBERIA ASCENDENTE QUE SE BIFURCA DE LA TUBERIA DESCENDENTE, SIENDO EL TAMANO, DEL FLUJO DE SOLIDOS TRANSPORTADO A TRAVES DE LA TUBERIA DESCENDENTE, VARIADA MEDIANTE EL SUMINISTRO VARIABLE DEL GAS TRANSPORTADO, DONDE EL NIVEL DE LOS SOLIDOS O LA EXISTENCIA DE SOLIDOS EN EL TANQUE DE SOLIDOS ES UTILIZADO COMO UN CONTROL VARIABLE, Y EL VOLUMEN DEL FLUJO DEL GAS TRANSPORTADO ES UTILIZADO COMO UNA VARIABLE ACCIONADORA DE UN CIRCUITO DE CONTROL. SE DESCRIBE TAMBIEN, UN APARATO PARA CONTROL QUE COMPRENDE UNA TUBERIA DESCENDENTE, UNA TUBERIA ASCENDENTE Y, UN SUMINISTRO DE GAS TRANSPORTADOR DEBAJO DE LA TUBERIA ASCENDENTE; ADEMAS DE, UN DISPOSITIVO DE MEDICION PARA DETECTAR EL NIVEL DE SOLIDOS, UNA VALVULA DE CONTROL PARA EL SUMINISTRO DEL FLUJO Y UN CIRCUITO DE CONTROL PARA VARIAR LA POSICION DE LA VALVULA DE CONTROL
