Abstract

The calorific values of wood pellets from different wood species were determined using a Parr 6300 bomb calorimeter, following the CEN/TS 14918:2005. The aim of this study was the thermo characterization of the wood pellets. Softwoods had a high calorific value between 19660.02 and 20360.45 kJ/kg, and the hardwoods had a ranging interval between 17631.66 and 20809.47 kJ/kg, in accordance to Phyllis distribution of HHV. The highest HHV (Higher Heating Value) and LHV (Low Heating Value) were obtained by Bowdichia nitida (20809.47–17907.85 kJ/kg). Cedrus atlantica was the softwood with the highest HHV (20360.45 kJ/kg). Pinus pinaster was the softwood with the highest LHV (16935.72 kJ/kg). Fagus sylvatica was the National hardwood with the highest HHV (19132.47 kJ/kg). Fraxinus angustifolia was the National hardwood with the highest LHV (16450.82 kJ/kg). Eucalyptus globulus obtained the lowest HHV and LHV (17631.66–14411.54 kJ/kg).
