Definitions

  • a wood load processing unit comprising a central volume, called technical volume or treatment, which is the part dedicated to the drying of wood, and the entrance locks and exit of the wood loads, located at the upstream ends and downstream of said central volume, and
  • the thermal means of dehydration or condensation may comprise liquid CO 2 diffusers, for diffusing liquid CO 2 into the gas stream. This diffusion of liquid CO 2 can be used to condense water vapor in the gas stream.
  • a step of drying the wood comprising:
  • the heat generation is carried out, in particular, by recovering the heat of a gas obtained by combustion at the outlet of the thermal generation means.
  • the gas, CO 2 under a heat transfer volume plus the volume that has been used for the condensation of water vapor, can then be recycled by the thermal system of the unit to be reused in the treatment cycle wood.
  • the process according to the invention thus describes a permanent loop for recovering CO 2 and operating heat. In these cycles, the only thermal energy consumed is in general the sensible heat that allows the temperature of the wood load to be treated to rise.
  • FIGS. 7a and 7b show an example of a heat transfer gas distribution system in a span / tunnel, with a view from above, a side view and a sectional view.
  • each wall 46d and 46g is sometimes the one through which the heat transfer gas is introduced and sometimes the one by which said heat transfer gas and water vapor are extracted.
  • the ceiling of the spans / tunnels 22 is also composed of two superimposed plates, forming the technical space 72 in which the distribution system of the
  • Zone management increases these parameters if there is insufficiency, or reduces them if the drying is too fast, or admits the injection of water, or of water vapor to regulate the drying, or stops the injection CO 2 if the zone goal is reached before the allotted time.
  • Liquid CO 2 is used in particular for:
