| 摘要 |
The invention relates to a method for roasting a plant biomass feedstock (B), comprising the following steps: generation of a treat gas stream using thermal generation means (G); generation of a layer of material at a high temperature, known as the thermal base; treatment of the biomass feedstock (B) with the treat gas stream, said treat gas stream being loaded with gas elements including water vapour and combustible pyrolysis gases originating from the biomass feedstock (B) during treatment; and recycling of at least one part of the water vapour by passing at least part of the laden gas stream through the above-mentioned thermal base. The invention also relates to a system for roasting a plant biomass feedstock (B). |
