Abstract :The paper aims to determine the physical properties insert ignore into journalissuearticles values(density); and calorific ones insert ignore into journalissuearticles values(calorific value and ash content); of pellets made of spruce and beech sawdust, thermally treated at temperatures of 170, 190 and 210 °C, for 1, 2 and 3 hours. After the thermal treatment of the sawdust, its mass loss was obtained, and compressed pellets were obtained under laboratory conditions. The results obtained from sawdust treatment indicated a weak increase in calorific value, depending on the temperature and the thermal treatment times. The final conclusion of the paper is that the thermal treatment improves the caloric properties of sawdust pellets, the beech sawdust having a higher capacity for torrefaction and compaction related to spruce sawdust.
