From the abstract
At a sawmill, the most energy demanding process is the wood drying. The drying process also has a great impact on quality parameters determined for the boards in the final sorting and thereby affects the sales value to a great extent. The objective of the work described in this compilation thesis was to find ways to improve the industrial wood drying process through better input, feedback and process itself. As input and feedback to the drying process, ways to improve the accuracy in estimating the moisture content (MC) was investigated. For the drying process itself, an investigation of the airflow distribution in a batch kiln at several different fan speeds was performed. Potential energy savings by introducing a new kiln layout was also investigated.
