The research cooperation in this activity has shown a fundamentally different attitude between the participating scientists in the scientific line of procedure considered. One group proceeds pragmatically. The group has the opinion that drying progress in big chip stacks is determined by so many intercorrelated factors that it is practically impossible to work out mathematical models of the drying progress. Therefore, the group conducts full scale field trials. Contrary to this attitude a more scientific line of procedure is maintained by other scientists. This line of procedure tries to establish the natural laws which determine drying of comminuted wood fuels. This is done by mathematical modelling and controlled laboratory experiments. Both types of experiment are described in this paper. |
