Yamada, A.(Hokkaido. Forest Products Research Inst., Asahikawa (Japan))
Sawdust and bark from factory waste, branches with leaves from forest residues, and mixture of charcoal and bark (weight ratio 1 : 1) were used as the raw materials of pellet fuel. Changes of moisture content caused by pelletizing and the relationship between the apparent specific gravity and bulk density of pellets were investigated. After air drying indoors, the gross calorific values and the proximate analysis values were measured. The gross calorific values were in the range from 19.7 to 26.8MJ/kg, and mixture of charcoal and bark showed the highest value. Moisture content was 7.4 - 9.3% in the air-dried. As for the ash content, bark had the highest value (6.0%). This value was about 20 times that of sawdust (0.3%).
