Abstract

The moisture content of densified biomass is a limit parameter influencing the quality of the solid biofuel. It influences its calorific value, density, mechanical strength and dimensional stability as well as the production process of this biofuel. The paper deals with the experimental research of the effect of moisture content of densified material on the final quality of biofuel in the form of logs. Experiments based on the single-axis densification of spruce sawdust were realized by hydraulic piston press, where the densified logs were produced under room temperature. The effect of moisture content on the quality properties of the logs, including density, change of moisture, expansion and physical changes, were studied. The results show the necessary moisture ranges for producing good-quality logs. The experiments were evaluated and the moisture content of the tested material was optimized to achieve the optimum value for the best quality of the solid biofuel.
