The invention relates to a method for avoiding and/or reducing the deposition
of volatile and non-volatile wood components in gas-bearing systems, whereby
at least one of the volatile wood components, at least partly, condenses in
the gas-bearing system and the gas contains at least one compound with a
similar condensation profile to the volatile wood component and which at least
reduces the deposition of volatile wood components or the reaction products
thereof. The invention further relates to a method for reducing and/or
avoiding the deposition of wood components on machines and/or equipment
components for the production of wood fibre material, from wood chippings, in
which the shredding of the wood is achieved in the presence of a compound
which forms a film on the surfaces of the above machines and/or equipment
components and at least reduces the deposition of volatile wood components
and/or the reaction products thereof.
La présente invention concerne un procédé pour éviter et/ou réduire les dépôts de composants volatils et non volatils du bois dans des systèmes conducteurs de gaz. Selon ledit procédé au moins quelques-uns des composants volatils se condensent au moins partiellement dans les systèmes conducteurs de gaz et le gaz contient au moins un composé qui présente un comportement de condensation semblable à celui des composants du bois volatils et qui réduit les dépôts des composants du bois volatils et/ou de leurs produits réactionnels. La présente invention concerne en outre un procédé pour réduire et/ou éviter les dépôts de composants du bois sur des machines et/ou des parties d'installations utilisées pour la production de matériaux en fibre de bois à partir de copeaux de bois, procédé selon lequel la trituration se fait en présence d'un composé qui forme un film sur les surfaces des machines et/ou des parties d'installations et qui, au moins, réduit les dépôts de composants volatils du bois et/ou de leurs produits réactionnels.
