Abstract

Salicaceae osier (Salix. Vmimalis) are one of the most cultured short rotations sprouts in the energetic plantatinions. These sprouts are willows which graving as bushes and have almost equal diameter and height of perenial stems. Preparing willows osier for the fuels, the trunks of trees are fell every four year, usually in the cold season. Willows osier are milling by various shreders in process after the removal of branches with leaves. Cutting willows in other seasons, the high moisture content leads to the biological activity of carving and other significant features. According experiments, the highest biological activity (800 to 340 W/(th)) are characterized by willow chaff from 50 to 33 % humidity. When the humidity seeks 12 %, the wood carving becames biological inactive. Moreover, it is observed that be actual density of willows wood is dried from 50 % to 12 % decrease from 800 kg/m3 to 600 kg/m3, and from his prepared chaff density - 400kg/m3 to 320 kg/m3.
