DETERMINATION OF DEPENDENCE OF WOOD BIOMASS DISINTEGRATION PARAMETERS ON WATER CONTENT

Abstract

Mechanical properties of wood are an important aspect in its processing. Wood is traditionally used for construction and technical purposes. Recently, its importance has grown in energy use. For energy use, it is necessary to modify the wood dimensionally into the desired shape. Therefore, the disintegration is an important operation in wood processing. Its difficulty depends on the properties of the wood.
The authors have determined the parameters of energy-using wood species on a water content in the range of 0-50%. The observed properties were wood shear stress. With decreasing water content, the shear stress of wood decreases. The shear strength limit of poplar wood increased from 22.3 MPa to 30.2 MPa. Poplar samples had a higher shear strength than willow samples.
