2. Thermally modified wood - Wikipedia

   en.wikipedia.org/wiki/Thermally_modified_wood

   Three of the processes are performed in one step, using oil (oil-heat treatment), nitrogen (Reti wood) and steam (Le-Bois Perdure). [1] The Thermo wood process consists of drying, heat treatment and finally cooling/conditioning, and takes up to 72 hours. [4]

3. Wood preservation - Wikipedia

   en.wikipedia.org/wiki/Wood_preservation

   These processes autoclave the treated wood, subjecting it to pressure and heat, along with nitrogen or water vapour to control drying in a staged treatment process ranging from 24 to 48 hours at temperatures of 180 °C to 230 °C depending on timber species. These processes increase the durability, dimensional stability and hardness of the ...

4. Pyrolysis - Wikipedia

   en.wikipedia.org/wiki/Pyrolysis

   Pyrolysis is most commonly used in the treatment of organic materials. It is one of the processes involved in the charring of wood [2] or pyrolysis of biomass. In general, pyrolysis of organic substances produces volatile products and leaves char, a carbon-rich solid residue.

5. Torrefaction - Wikipedia

   en.wikipedia.org/wiki/Torrefaction

   Torrefaction is a thermochemical treatment of biomass at 200 to 320 °C (392 to 608 °F). It is carried out under atmospheric pressure and in the absence of oxygen.During the torrefaction process, the water contained in the biomass as well as superfluous volatiles are released, and the biopolymers (cellulose, hemicellulose and lignin) partly decompose, giving off various types of volatiles. [4]

6. Wood drying - Wikipedia

   en.wikipedia.org/wiki/Wood_drying

   A dehumidification chamber can be an unvented system (closed loop) or a partially vented system which uses a heat pump to condense moisture from the air using the cold side of the refrigeration process (evaporator.) The heat thus gathered is sent to the hot side of the refrigeration process (condenser) to re-heat the air and returns this drier ...

7. Heat treating - Wikipedia

   en.wikipedia.org/wiki/Heat_treating

   Heat treating furnace at 1,800 °F (980 °C) Heat treating (or heat treatment) is a group of industrial, thermal and metalworking processes used to alter the physical, and sometimes chemical, properties of a material. The most common application is metallurgical.
