Abstract:
The activity was aimed to identify the best raw material suitable for pellet production. The experimentation was carried out using poplar plantations at the end of the ninth year of age using whole trees, stems without branches and branch/treetops. The dendrometric characteristics of the trees and the qualitative characteristics of the pellets produced were assessed. Some parameters, such as the heating value and moisture content, ashes and melting point were determined before and after pelleting in order to identify any differences directly related to the transformation process. The work concludes a previously presented work that concerned the production and characterization of pellets starting from 3 and 6–years–old poplar. The pellets produced with nine–years–old poplar wood reach the requirements of class A1 for diameter, length, moisture content, ash melting point, lower heating value. A general improvement of quality parameters was observed by transforming the poplar wood chips into pellets in terms of ash content and ash melting point. Furthermore, the use of the branches in the production process seems to influence the physical parameters of the pellet, more than the energetic ones.
