Relationship between technological and material parameters during densification of beech sawdust

摘要

Densification is very suitable and important technology at biomass treatment before its energy recovery. During the biomass densification can be recognized various technological and also material parameters which significantly influence the final solid biofuels quality. The paper deals with the experimental research of the relationship between technological and material parameters during densification of beech sawdust. The main goal of presented experimental research is to determine the relationship between pressing pressure, pressing temperature and material fraction size. Described experimental research was realized by single-axis densification. The impact of fraction size with interaction of pressing pressure and pressing temperature on the quality properties of briquettes was determined. These parameters interaction effects the final solid biofuels (briquettes) quality. From briquettes production point of view and also from densification machines constructions point of view is very important to know about mutual interaction of these parameters on final briquettes quality. The experimental findings presented here are showing the importance of mentioned parameters during the densification process.
