Abstract

Dans un réacteur à lit fluidisé en circulation on crée un lit de particules dans la canalisation de retour (34) pour recycler les particules provenant du séparateur de particules (14) vers la chambre de combustion (12). Des ouvertures d'entrée (50) s'étendent depuis le lit de particules jusque dans la chambre de combustion, et la hauteur du lit de particules est maintenue au-dessus des ouvertures d'entrée à une distance suffisante pour former un joint étanche au gaz. Les particules du lit sont fluidisées et des ajutages de transport (52, 54, 56, 58, 59) sont agencés à différents niveaux pour transporter les particules depuis le lit jusque dans la chambre de combustion à travers les ouvertures d'entrée. Des échangeurs de chaleur (38), des surchauffeurs par exemple, peuvent être placés dans le lit pour récupérer la chaleur dégagée par les particules.
