Energy Efficient Wood Fuel Drying

Abstract: With reference to the reduction of carbon dioxide emissions, biofuel is pointed out as an important substitute for fossil fuels. The Swedish Government favours the use of biofuel by imposing taxes on fossil fuels. However, biofuel is a limited resource and it is therefore important that we develop efficient systems for the production and utilization of this limited resource.



This thesis is based on six papers out of which five are experimental and treats the drying of wood in spouted bed co-generation dryers. The sixth paper deals with the integration of a co-generation dryer into the energy system of a sawmill.
