Briquetting of Poplar Wood from Short Rotation Coppice—The Effects of Moisture Content and Hammer Mill Screen Size

Studies on the use of biomass from short rotation coppices for briquette production as a sustainable biofuel have been scarce in literature. This study investigated effects two process variables, hammer mill screen size at three levels (5.3, 10.3, and 25.4 mm) moisture content (13.6, 19, 25% (w.b.)), properties briquettes poplar Max-4 trees. The whole tree was divided into fractions, crown stem, were produced them. variables compressed density, relaxed relaxation ratio, shatter index analyzed. results showed that combined interaction had no significant (p > 0.05) ratio briquettes. However, both significantly influenced irrespective fraction < 0.05). Hammer sizes 5.3 10.3 mm contents 13.6 19% (w.b.) resulted good quality across stem fractions. shows high-quality can be woody biomass.
