Abstract

L'invention porte sur une chaudière à lit fluidisé circulant comportant un système réchauffeur d'air, comprenant un four pour la combustion de combustible solide particulaire avec de l'air primaire injecté dans le four par une grille de fond et de l'air secondaire injecté dans le four par les parois du four; un passage de gaz de combustion raccordé au four pour l'évacuation du gaz de combustion et de particules entraînées avec celui-ci à partir du four; un séparateur de particules pour la séparation des particules du gaz de combustion; une canalisation de retour pour le renvoi de particules séparées provenant du séparateur de particules vers le four; et une chambre d'échange de chaleur à lit fluidisé pour la récupération de chaleur à partir des particules amenées dans celle-ci à partir du four, la chambre d'échange de chaleur à lit fluidisé comprenant un moyen d'entrée pour amener les particules provenant du four dans la chambre d'échange de chaleur à lit fluidisé; un moyen de sortie pour ramener les particules provenant de la chambre d'échange de chaleur à lit fluidisé vers le four; et un moyen pour injecter un second gaz de fluidisation dans la chambre d'échange de chaleur à lit fluidisé, le système réchauffeur d'air comprenant un réchauffeur d'air primaire disposé dans une première partie du passage de gaz de combustion pour le réchauffage de l'air primaire et de l'air secondaire et un réchauffeur d'air pour le réchauffage du second air de fluidisation disposé dans une seconde partie du passage de gaz de combustion, laquelle seconde partie du passage de gaz de combustion est raccordée en parallèle avec la première partie du passage de gaz de combustion.
