THE INFLUENCE OF SOME FACTORS ON THE TIMBER DRYING PROCESS, ANALYZED BY A GLOBAL SIMULATION MODEL

A model for the simulation of timber drying in a batch kiln has been used for the investigation of a set of different questions related to this drying process. The model is global in the sense that it takes into account that the drying air local climate changes as it passes through the kiln load. In...

The model is global in the sense that it takes into account that the drying air local climate changes as it passes through the kiln load. In Scandinavian, practice kiln stacks are normally built from boards of random lengths so that every second board is located flash at one end of the stack and the other boards flash at the other end. This kiln stack geometry is also included, as well as airflow reversal. This model has been utilized to investigate the following situations:The effect of sticker thickness on airflow, drying time and final MC standard deviation is illustrated. Thicker stickers mean less timber in a given kiln, but results in shorter drying time. The kiln drying capacity is not influenced very much, but the final MC spread is decreased. The influence of kiln parameters on the final MC standard deviation is investigated and simple formulas are presented for the estimation of this variationinfo:eu-repo/semantics/openAccessUniversidad del Bío-BíoMaderas.
