A humidity chamber (ESPEC CORP, Japan; Model: LHU-113) was
used for the measurement of the saturated moisture content of
pellets. Before the moisture uptake tests, wood pellets were dried
in the THELCO laboratory PRECISION oven at 105 °C for 24 h. Then,
wood pellets were placed in a Petri glass dish and put into the humidity
chamber. During the weight measurement, the Petri dish
was covered with a glass cap to reduce themoisture loss. For the saturatedmoisture
content, wood pellets were placed in the chamber at
30 °C and 90% relative humidity for at least 48 h [8].
