Pellets and briquettes from fruit trees wood
Journal Title: Annals of Warsaw University of Life Sciences- SGGW - Agriculture - Year 2015, Vol 66, Issue 66
Abstract
The objective of the study was to determine the physical characteristics of biomass from apple tree branches of Idared, Gloster and Cortland varieties and pellets and briquettes made of it. Crushed biomass was used to prepare briquettes and pellets on a knife shredder with a sieve of mesh size of 25 x 8 or 23 x 4 mm. For biomass, the moisture content and particle size characteristics were determined; for pellets and briquettes, density and bulk density referring to dry mass and combustion heat, calorific value and technical durability, as well as strength parameters: modulus of elasticity, maximum stress, as well as shear, compression force and bending force measured by a two-point test of the agglomerate. Research was conducted in accordance with the appropriate standards. The results of assessment of physical characteristics of pellets were higher than those of the briquettes and lower than required by the standards under concern. The values of strength parameters were strictly connected with agglomerate durability.
