In the present work, a study of the thermal drying process of biomass residues has been developed. The residues used were woodchips which have been dried in a thermal cylindrical dryer designed according to these types of residues. An experimental facility has been built in order to measure the temperature inside the dryer. The raw material was characterized by elemental and proximate analyses as well as by Higher Heating Value. Hot gases and air were used as drying medium using different flow rates. The experiments were carried out at various drying medium temperatures. The rotation speed of the dryer screw was varied for each experiment. The biomass residue was fed to a dryer and dried many times in the same drying conditions in order to determine the reduction of moisture content and temperature variation of the residue along the time. The variation of moisture content and drying temperature are determined under different drying conditions. It was found that by increasing drying medium flow rate and decreasing the rotation speed of the screw, the drying rate is increased. Finally, it could be concluded that the dried biomass residue can be used as a solid fuel with a moisture content of about 10% in direct combustion to produce thermal energy, and in gasifying processes to produce syngas. |
