Résumé
This work aims at investigating the effects of feedstock properties and compaction force on the physicochemical properties of densified fuel briquettes issued from the co-processing of 3 biomass types (namely wood sawdust (S), miscanthus (M) and wheat straw (WS)) using a hydraulic press machine. To that end, we built a design of experiments integrating two compaction forces (225 and 450 kN), two particle sizes (<1.25 mm and comprised in the 1.25-2.5 mm range) and five proportions of each biomass (ranging from 0 to 100%) in S/M, S/WS and M/WS blends. The intrinsic quality of the obtained fuels was assessed by determining their apparent density, and ash, volatile matter, and fixed carbon contents. The results obtained showed that all the above densification parameters influence the apparent density of the produced briquettes. Values ranging from 512 to 1121 kg·m-3 were measured, with the highest one determined when considering a high compaction force, small wood particles, and a wood proportion of 100 wt%. Increasing the wood content from 0 to 100 wt% was, moreover, shown to decrease the proportion of ash in the produced briquettes while enhancing their wt% in volatile matters, thus translating into increased fuel energy contents as exemplified by computed net calorific values going from 15.22 to 19.12 MJ·kg-1.
