Etude de l'évolution des caractéristiques physico-chimiques des plaquettes forestières en fonction des modalités de stockage et de séchage

Abstract : To answer actual and future energetic and environmental issues, wood development is very important, notably with industrial and collective applications. To answer these needs and follow this development, lots of supplying structures of wood chips are being created. The main difficulty for these companies is guaranty good and stable raw material quality all time, notably concerning moisture content. The objective of this work is to research the most appropriate solutions to answer this problematic. So, the work begins by a bibliographical study that will help to understand the existing systems of drying; drying can be natural (under layer, under shelter...) or artificial (tunnel dryer, rotary dryer...). Then, experiments were put in place to understand and quantify more precisely natural drying parameters impact on wood chips and physico-chemical modifications on wood chips during storage. After, mathematic models are developed to traduce wood chip drying comportment, after models results are compared to experimental results. Finally, economical scenarios were performed to study the different solutions or combinations of solutions to dry wood chips in order to answer technical and economical industrial needs.
