CA 2274944

The invention concerns an apparatus for the heat treatment of lignocellulosic material, and comprises a chamberfor the treatment of the material, at least one combustion chamber (30) with at least one burner (31) functioning in a reducing atmosphere, stirring mechanisms (26, 26') to ensure the circulation of gases in the treatment chamber so that a part of the gases originating from the chamber circulate across the combustion chamber (30). The invention further relates to a corresponding treatment process comprising the following steps: preheating and drying of the material at a temperature akin to that of saturated liquid; heating of the material in a reducing atmosphere; cooling of the material by the injection of water vapor. The first two steps can be automatically controlled by regulating the burner or burners so that the difference between the temperature outside and that within the material remains substantially constant.

L'invention concerne un dispositif de traitement à haute température de matériau ligno-cellulosique, comprenant une chambre de traitement du matériau, au moins une chambre de combustion (30) avec au moins un brûleur (31) fonctionnant en atmosphère réductrice, des moyens de brassage (26, 26') assurant une circulation des gaz de la chambre de traitement de sorte qu'une partie des gaz provenant de la chambre circule à travers la chambre de combustion (30). Elle concerne aussi un procédé de traitement correspondant, comprenant les étapes de préchauffage et séchage du matériau à une température voisine de la température de vaporisation de l'eau; chauffage du matériau en atmosphère réductrice; refroidissement du matériau par injection de vapeur d'eau. Un pilotage automatique du traitement pendant les deux premières étapes peut s'effectuer en contrôlant le ou les brûleurs de sorte à maintenir une différence sensiblement constante entre la température à l'extérieur et au sein du matériau.
