Title (EN) METHOD AND DEVICE FOR THE HIGH-TEMPERATURE HEAT TREATMENT OF LIGNEOUS MATERIAL
(FR) PROCEDE ET DISPOSITIF DE TRAITEMENT THERMIQUE HAUTE TEMPERATURE DE MATIERE LIGNEUSE
Abstract:
(EN) The invention relates to a method and device for the high-temperature heat treatment of a ligneous material such as wood, in an ecological and uncomplicated manner while preserving the characteristics and dimensional stability of this wood in the existence of humidity, having an optimized efficiency and limiting the risks of explosion. The device (1) comprises a treatment enclosure (2) filled with a coolant medium (P) circulating in a continuous manner inside the treatment enclosure (2) and successively passing through a condenser (50) coupled to a combustion chamber (52) in order to extract resins and water vapor contained in the coolant medium. The inventive device also comprises a heating chamber (60), which is provided for heating the coolant medium (P) and which is equipped with a burner (61). Injection chambers (30, 31) are also provided for re-injecting the coolant medium into the treatment enclosure (2) by means of an injection chamber (30, 31). The invention is used for carrying out high-temperature heat treatment of ligneous material.
(FR) L'invention concerne un procédé et un dispositif de traitement thermique haute température d'une matière ligneuse telle que du bois, écologique, peu onéreux, destinés à préserver les caractéristiques et la stabilité dimensionnelle de ce bois en présence d'humidité, ayant un rendement optimisé et limitant les risques d'explosion. Le dispositif (1) comporte une enceinte de traitement (2) remplie d'un fluide caloporteur (P) circulant de manière continue dans l'enceinte de traitement (2), traversant successivement un condenseur (50) couplé à une chambre de combustion (52) pour extraire les résines et la vapeur d'eau contenues dans le fluide caloporteur, une chambre de chauffage (60) du fluide caloporteur (P) pourvue d'un brûleur (61), des chambres d'injection (30, 31) pour réinjecter le fluide caloporteur dans l'enceinte de traitement (2) au moyen d'une chambre d'injection (30, 31). Application : traitement haute température de matière ligneuse.
