Relation between combustion heat and chemical wood composition during white and brown rot

摘要: The results of respective investigations indicate that during white rot the combustion heat wood (Qexp (J/g)) remained virtually unchanged and at greatest extent decomposition it was in range also found non-rotten wood. During brown samples increased, beginning a weight loss 20–30%. difference between Qexp weighted mean values isolated chemical components (Qcal) were neglectable. If measured for each sample taken as 100%, then Qcal averaged from 101.1–105.6% 97.4–108.2% rot, respectively. calculation error is expressed coefficient k; varies depending on accuracy selectivity separation methods used.
