Abstract

UN REACTOR DE LECHO FLUIDIZADO QUE INCLUYE UN APARATO DE FILTRO PARA LA SEPARACION Y RECICLADO DE LAS PARTICULAS FINAS QUE SON ARRASTRADAS POR LOS GASES DE COMBUSTION. EL ALOJAMIENTO DEL APARATO DE FILTRO TIENE UNA PLURALIDAD DE TUBOS DE FILTRACION CERAMICOS DISPUESTOS VERTICALMENTE. LA CAMARA DEL REACTOR Y EL ALOJAMIENTO DEL FILTRO ESTAN DISPUESTOS ADOSADOS Y TIENEN UNA PARED COMUN ENTRE ELLOS. UN PRESEPARADOR PARA LA SEPARACION DE LAS PARTICULAS MAS GRUESAS ESTA PREVISTO, EL CUAL, CONECTA LA CAMARA DEL REACTOR CON EL APARATO DEL FILTRO. EL REACTOR, EL SEPARADOR Y EL APARATO DE FILTRO ESTAN ENCERRADOS EN UN RECIPIENTE CILINDRICO A PRUEBA DE PRESION. LAS PAREDES DE LA CAMARA DEL REACTOR Y EL ALOJAMIENTO DEL FILTRO PUEDEN SER REFRIGERADAS POR AGUA. EN OTRA FORMA, EL FILTRO ESTA COMPUESTO POR UNA PLURALIDAD DE PLACAS POROSAS TENIENDO NERVIOS QUE EMPALMAN LAS PLACAS ADYACENTE PARA DEFINIR PASILLOS A TRAVES DEL FILTRO.
