Abstract
L'invention concerne un système et un procédé de calcination à lit fluidisé. Ledit système comporte un filtre pour les gaz résiduels s'échappant du lit qui est divisé en plusieurs compartiments pouvant être mis tour à tour dans le circuit de filtration et en phase de soufflage à contre-courant. Application à la calcination de matières particulaires.
