Process gases, in particular process waste gases from refuse incineration, are introduced into a circulating fluidized bed from below via a venturi-nozzle-like inlet and form a core stream (K). Auxiliary-gas flows (H) are injected in a annular marginal zone (6) concentrically to the core stream (K) into the circulating fluidized bed. The fluidized-bed solid particles sinking to the bottom in marginal regions of the fluidized bed are thereby delivered into the core stream (K).
Des gaz de procédé, en particulier des gaz de combustion d'un incinérateur de déchets, sont introduits par le bas dans un lit fluidisé circulant, au moyen d'un orifice d'injection à étranglement pour former un flux primaire (K). Des flux gazeux secondaires (H) sont injectés dans le lit fluidisé par une zone marginale annulaire (6) dont l'axe coïncide avec celui du flux primaire (K). Les particules solides du lit fluidisé qui décantent dans les zones marginales du lit fluidisé sont ainsi entraînés dans le flux primaire (K).
