ABSTRACT

This study is related to drying of wood chips as a preconditioning step for wood pellet production. This article presents experimental data which are important in designing an industrial drying process: initial moisture content, bulk density, bulk porosity and desorption isotherm. Five wood species from the boreal forest have been investigated and two initial hydric states were considered, i.e. green state and pre-dried state. Desorption isotherms have been modelled using the GAB model, whose constants have been determined using a linearization method.

五种北方森林木片的初始含水量、堆积密度、堆积孔隙率和解吸等温线

摘要

本研究涉及将木片干燥作为木屑颗粒生产的预处理步骤。本文提供了对设计工业干燥过程很重要的实验数据：初始水分含量、堆积密度、堆积孔隙率和解吸等温线。对来自北方森林的五种木材进行了调查，并考虑了两种初始含水状态，即绿色状态和预干燥状态。解吸等温线已使用 GAB 模型建模，其常数已使用线性化方法确定。
