Abstract:
The last decade has been characterized by the growth of demand of wooden pellet. This has led consumers and producers to an increase in attention towards pellets quality. Among pellets quality parameters, geometrical ones such as length and diameter, are hardly considered by industry operators. Nevertheless, pellet length is particularly important since it affects how this form of biofuel fills the available spaces,impacting on biofuel feeding capacity, namely the mass flow rate (MFR). Currently, technical standard ISO 17225-2 does not consider MFR as a key parameter for the assessment of biofuels quality. Nevertheless, the authorsbelieve that paying more attention to geometrical parameters and their influence on MFR could translate into an increase in energy efficiency.Preliminary resultsallowed to assess an inverse relation between the average length of samples and MFR.In particular, it has been obtained a 15% difference in MFR between samples with higher and lower average length values.
