Abstract

LA INVENCION SE REFIERE A UN REACTOR DE LECHO FLUIDO CIRCULANTE QUE TIENE PAREDES SUBSTANCIALMENTE VERTICALES CON ELEMENTOS ENFRIADORES EN LAS MISMAS, LAS PAREDES VERTICALES DEFINEN EL INTERIOR DE LA CAMARA DEL REACTOR (14). UN SEPARADOR (22) PARA SEPARAR EL MATERIAL EN PARTICULAS DE LOS GASES DE ESCAPE SE CONECTA A LA SECCION SUPERIOR DE LA CAMARA DEL REACTOR. UN CONDUCTO DE RETORNO (26) SE CONECTA AL SEPARADOR. UN LECHO FLUIDO BURBUJEANTE (28'') SE DISPONE DE FORMA ADYACENTE AL REACTOR Y ESTA PROVISTO DE MEDIOS INTERCAMBIADORES DE CALOR. UN CANAL DE DESCARGA DE SOLIDOS (38) SE DISPONE ENTRE LA CAMARA DE LECHO FLUIDO BURBUJEANTE Y LA CAMARA DEL REACTOR. EL CANAL DE DESCARGA TIENE UNA ABERTURA EN LA SECCION SUPERIOR DEL MISMO PARA PERMITIR QUE EL MATERIAL EN PARTICULAS SEA DESCARGADO DESDE LA SECCION SUPERIOR DEL MISMO. LA INVENCION TAMBIEN SE REFIERE A UN METODO PARA OPERAR UN REACTOR DE LECHO FLUIDO CIRCULANTE CON UN CANAL DE DESCARGA ENTRE UN LECHO FLUIDO BURBUJEANTE Y LA CAMARA DEL REACTOR. EL MATERIAL EN PARTICULAS ENFRIADO ES DESCARGADO DESDE LA SECCION INFERIOR DEL LECHO FLUIDO BURBUJEANTE AL INTERIOR DE LA SECCION INFERIOR DEL CANAL DE DESCARGA. EL MATERIAL EN PARTICULAS SE FLUIDIZA EN EL CANAL DE DESCARGA Y SE INTRODUCE DESDE LA SECCION SUPERIOR DEL MISMO AL INTERIOR DE LA CAMARA DEL REACTOR.
