Abstract

L'invention concerne un procédé de traitement de lignite humide, notamment pour une exploitation thermique dans une chaudière de centrale. Le lignite brut est d'abord fragmenté puis concassé dans au moins une installation de concassage (2) avant d'être amené dans un espace de séchage en aval. Le séchage est réalisé dans un lit fluidisé en utilisant un séchoir en lit fluidisé (3) à chauffage indirect. Une partie du lignite sec extrait du séchoir en lit fluidisé (3) est déviée et mélangée à nouveau au lignite brut avant le séchage, le lignite ayant ainsi une aptitude améliorée à la fluidisation.
