The moisture content of the wood has negative impact on transport, storage and use of wood, particularly this can be noticed on firewood. The moister the wood the harder is the transportation and storing. The high percentage of moisture also reduces the heating power of fire wood.
Drying of the wood of different tree species was studied at the forestry institute Tuomarniemi with following experiment setup: pines, spruces, birches, aspens and alders were logged and cut into one-meter split billets. Then they were dices according Huber’s formula. The wood was stacked in three similar ricks (stacks), varying the direction of the cut surface. The various tree species were distributed evenly to every rick. The split billets were weighted straight after manufacturing and after every month.The wood dries fastest during spring and summer months. The direction of the cut surface of split billets in the rick makes no big differences in drying. The coniferous wood dries up to lower moisture content than broadleaved woods.
