THE INFLUENCE OF SIZE FRACTION AND MOISTURE CONTENT ON THE COMPRESSIBILITY OF WOOD SAWDUST IN EFFECTIVE PROCESS OF PRODUCTION A SOLID BIOFUEL

Popis výsledku v původním jazyce

Many technological factors (size fraction, moisture content, and others) have major effect on the densification process of biomass to the form of high-grade solid biofuel. The basic parameter describing the densification process of particulate matter is its compressibility, quantified by the coefficient of compressibility. Knowing this coefficient for a specific material like wood sawdust is a basic prerequisite for the application of compressibility equations describing the densification process, and for calculating the workload in the production process of high-grade solid biofuel. This paper deals with a methodology for determining the compressibility factor for sawdust on the basis of experiments to quantify pine sawdust. The experiments were performed in two stages. The first stage was an experimental investigation of the influence of size fraction and moisture content on the final compressibility of pine sawdust. Highpressure binderless densification of pine processing residues in the form of sawdust was studied. A piston-and-die process was used to produce densied briquettes under room temperature and at pressure up to 159 MPa. The results show the behaviour of the pressure load when the parameters of the particulate matter are changed. In the second stage, the experiments were evaluated and optimized to achieve minimum energy input of the process and a maximum degree of densification. The research results will be used to develop new technologies and machinery for effective biomass densification to achieve a high-grade solid biofuel.
