<p>An apparatus (100) for the thermal-chemical modification treatment of wood is described, in which such a modification is obtained through multiple chemical reactions of the substances comprising the wood structure generated by exposing the wood to temperatures at which the pyrolysis phenomenon begins, i.e., in the range of 180 °C-240 °C. The apparatus (100) comprises a vacuum autoclave-cell (1) and a cooling system with thermal exchange and forced circulation of fluid comprising a circulation seat (8, 15A, 15B) of the fluid, comprising a thermally conductive confinement wall having an exposed surface within the vacuum autoclave-cell (1) and having an opposite surface touched by said forced circulation of fluid, so that said circulation of fluid may subtract heat from the atmosphere inside the vacuum autoclave-cell (1), thus avoiding to directly contact the internal atmosphere.</p> |
