Abstract

L'invention concerne un procédé de traitement thermique d'objets en bois (1) dans un autoclave (2), sous pression et/ou vide, de préférence à une pression proche de celle de la vapeur saturée, et de manière à pouvoir réduire la quantité d'oxygène dans l'autoclave (2) avant le traitement thermique. On peut ajouter ultérieurement une forme de gaz de protection pour réduire la carbonisation des objets en bois (1). L'invention concerne également un système de traitement d'objets en bois (1) dans un espace chauffé constitué d'un autoclave (2) relié à un système de pression (3), pour le réglage de la pression dans le système, et relié aussi à un contenant de condensat (4). Il existe en outre un égaliseur de pression dans l'autoclave et une unité de serrage des objets en bois et/ou de serrage des objets en bois entre eux, pour éviter l'éclatement ou la torsion durant ou après le traitement.
