Abstract

UNA CAMARA DE UN REACTOR (12, 112, 312) DE UN REACTOR DE LECHO FLUIDO (10) TIENE CIRCULACION INTERNA DE PARTICULAS. NO SE PERMITE QUE LAS PARTICULAS RECIRCULADAS, MAS GRANDES SE PONGAN EN CONTACTO CON LAS SUPERFICIES DE TRANSFERENCIA DE CALOR (40, 140) MEDIANTE LA CLASIFICACION DE LAS PARTICULAS ADYACENTES A LOS FONDOS (24, 124, 224) DE LA CAMARA DEL REACTOR (12, 112, 312) USANDO UNA CAMARA DE PARTICULAS (22, 122, 222, 322) QUE TENGA UNA PARED DE BARRERA (30, 130, 230, 330) CON ORIFICIOS (50) O RANURAS (52) DE UNA DIMENSION MAXIMA DE ALREDEDOR DE 30 MM. LAS SUPERFICIES DE TRANSFERENCIA DE CALOR (40, 140) PUEDEN DISPONERSE EN LA CAMARA DE PARTICULAS (22, 122, 222, 322). LAS PARTICULAS MAS GRANDES FLUYEN HACIA ABAJO DE LAS PAREDES DE LA CAMARA DE PARTICULAS AL INTERIOR DE LA CAMARA DEL REACTOR, Y ALGUNAS PARTICULAS FINAS DENTRO DE LA CAMARA DE PARTICULAS SE HACEN CIRCULAR PREFERIBLEMENTE DE NUEVO HACIA EL LECHO FLUIDO. LA PARED DE BARRERA ES PREFERIBLEMENTE LA PARED SUPERIOR DE LA CAMARA DE PARTICULAS, Y PUEDE ESTAR REVESTIDA DE FORMA REFRACTARIA CON SURCOS (54), Y/O PUEDE ESTAR FORMADA DE TUBOS DE AGUA (64) CONECTADOS ENTRE SI MEDIANTE ALETAS (66), ESTANDO LOS ORIFICIOS O RANURAS FORMADOS EN LAS ALETAS.
