【 摘 要 】

The mutual interaction between pellets quality, which is represented by the pellets physical properties, and the input composition of raw material is very interesting and complicated itself. Therefore, the main aim of this research paper is to determine the relationship between the raw material composition, which influences the pellets quality and the pellets quality indicators - physical properties of pellets. During the biomass densification, also the raw material properties significantly influence the final solid biofuels quality. Therefore the raw material composition represented by different mixtures from spruce sawdust, wheat straw and spruce bark, in various ratios (90/10, 80/20, 50/50, 80/10/10 and 50/30/20) and in various raw material composition (sawdust/straw, straw/bark, straw/sawdust/bark) were investigated. During this research study in total 14 different material composition was used. Effect of mentioned raw material mixtures on pellets bulk density, mechanical durability, abrasion, particle density and hardness were determined. Research findings presented in this paper are based on a realized experimental research that was done on Faculty of Mechanical Engineering STU in Bratislava. This experimental research was a logical result of and based on authors practical experience and wide theoretical analyses of selected variables influence. Described experimental research was realized by real pelleting machine that is a part of semi-production pelleting plant on Faculty of Mechanical Engineering STU in Bratislava. The experimental findings presented here are showing the importance of mentioned variables and parameters during the pelletizing process.
