Quality Analysis of Commercially Available Wood Pellets and Correlations between Pellets Characteristics

In this study, the quality of wood fuel pellets, commercially available in Greek market, was evaluated using ISO 17225 Standard Requirement Thresholds as a benchmark. The examined criteria were calorific value, ash content, mechanical durability, bulk density and moisture content. reliability information on packages evaluated. Meanwhile, potential correlation between most crucial qualitative properties pellets investigated to elucidate their contribution pellets’ estimation. Most pellet brands showed low content acceptable values for residential use—although half found be lower than that reported, mainly with regard durability density. application two different collection periods highlighted stability over time. Higher value seemed provided by which had mechanically durable. As regards specific samples, dark colour high roughness correlated (impact 56.2% 43.6%, respectively).
