A system for drying a load of wood including: a heat generating device providing heat necessary for drying the load of wood, apparatus for generating a gaseous coolant flow for treating the load of wood by combustion of biomass under O2, the gaseous coolant flow being essentially constituted by CO2, a heat exchange device allowing the transfer of the heat produced by the heat generating device to the gaseous coolant flow for treating the load of wood, a unit for treating/drying the load of wood, including a central volume, known as a technical or treatment volume, dedicated to the drying of the wood, and inlet and outlet hatches for the loads of wood, situated at the upstream and downstream ends of said central volume, and a thermal device for the dehydration and condensation of the steam extracted from the wood during the drying cycle.
1) System for drying a load of wood (23) comprising:
3) System according to any one of the preceding claims, characterized in that it also comprises means for continuously recycling the gaseous flow for treating the load of wood (23).
4) System according to any one of the preceding claims, characterized in that the central volume (21) of the treatment unit (20) is divided into substantially identical drying bays (22), which form tunnels in which the load of wood (23) to be treated follows a continuous cycle.
21) System according to any one of the preceding claims, characterized in that the thermal dehydration or condensation means (11) comprise liquid CO2 diffusers (78).
22) System according to any one of the preceding claims, characterized in that it comprises a fan/extractor (12) for collecting the gaseous flow after treatment.
24) System according to any one of the preceding claims, characterized in that it also comprises means for mixing the gaseous flow at the outlet from the condensation or dehydration means (11) with the gaseous treatment flow.
25) System according to one of the preceding claims, characterized in that it also comprises means for collecting and pressure-boosting, in a tank, the water condensed in the condensation and dehydration means (11).
26) System according to any one of the preceding claims, characterized in that the heat generating means comprise means of combustion (191) of solid fuel.
29) System according to any one of the preceding claims, characterized in that the heat exchange means comprise at least one heat exchanger (17).
30) System according to one of the preceding claims, characterized in that it also comprises means for distributing low-pressure steam in order to regulate the drying stress, over the load of wood (23) to be dried.
35) System according to any one of the preceding claims, characterized in that the inlet (24) and outlet (25) hatches comprise means (50) allowing a lateral movement of the carriages (30).
36) System according to one of the preceding claims, characterized in that it also comprises means of communication between the different components of said system.
37) Bio-thermal method for drying a load of wood (23), implemented in the system according to any one of the preceding claims, comprising:
