Influence of the Stalk Orientation on the Mechanical Properties of Biomass Briquettes

D. Ancans, A. Kakitis & I. Nulle
Particle size and shape are of great importance for briquetting. It is generally agreed that biomass material of 6­8 mm size with 10­20% powdery component (< 4 mesh) gives the best results. Calculated energy ­1 ­1 consumption for hemp stalk cutting to mentioned size is > 12 kJ kgbut for size 100 mm it is <1 kJ kg. The goal of the investigation is to obtain the necessary density and durability of reed, straw and...
