Abstract

LAS PARTICULAS QUE SE ENCUENTRAN EN UN REACTOR DE LECHO FLUIDIFICADO (EJ. UN REACTOR DE LECHO FLUIDIFICADO CIRCULANTE) SE DESCARGAN DE LA CAMARA DEL REACTOR (10) Y A CONTINUACION SE REFRIGERAN (SE RECUPERA EL CALOR DE ELLAS) EN UNA CAMARA DE TRATAMIENTO (16). ESTO SE LLEVA A CABO DE FORMA PARTICULARMENTE VENTAJOSA SI SE DESCARGAN LAS PARTICULAS DE LA CAMARA DEL REACTOR A UN PRIMER NIVEL (EJ. A TRAVES DE UNA OBTURACION NO MECANICA O UNA PARED DE CLASIFICACION) EN UNA CAMARA DE ELEVACION (14). EL GAS QUE FLUYE DENTRO DE LA CAMARA DE ELEVACION ARRASTRA LAS PARTICULAS Y LAS LEVANTA HACIENDOLAS ENTRAR EN LA CAMARA DE TRATAMIENTO. TRAS EL TRATAMIENTO, SE HACE VOLVER A LAS PARTICULAS QUE SE ENCUENTRAN EN LA CAMARA DE TRATAMIENTO A LA CAMARA DEL REACTOR A UN NIVEL SUPERIOR QUE EL PRIMER NIVEL, EN CUYO PUNTO LA PRESION EN LA CAMARA DE TRATAMIENTO ES MAYOR QUE LA PRESION EN LA CAMARA DEL REACTOR. LAS PARTICULAS SE PUEDEN CLASIFICAR EN LA CAMARA DE ELEVACION UTILIZANDO UN GAS FLUIDIFICANTE PARA TRANSPORTAR LAS PARTICULAS SOLIDAS DE MENOR TAMAÑO QUE UN TAMAÑO PREDETERMINADO A LA CAMARA DE TRATAMIENTO MIENTRAS LAS PARTICULAS DE MAYOR TAMAÑO SE DESCARGAN DEL FONDO (38) DE LA CAMARA DE LEVANTAMIENTO.
