ABSTRACT

The quality of briquettes produced of a mixture of wood particles, sawdust and dust by perpetual screw briquette machines with a heated mould matrix was tested and the stability of the production process was analysed. The moisture content and fractional composition of the waste products used for briquettes production along with the moisture content, density and degree of pressing of briquettes were determined. The quality of briquettes assessed on the basis of the macroscopic structure and physical parameters was very good. Their density was close to 1200 kg·m^-3, the moisture content of about 3%, their external surface was smooth and their cross-section structure homogeneous. The good quality briquettes were characterised by proportional contribution of particular fractions of the lignocellulose blend. The most important reason for the instability of briquette production process was found the inhomogeneous distribution of wood dust and not the size of its fraction in the bulk of the lignocellulose mass introduced into the briquetting machine.

Key words: lignocellulose waste, perpetual screw briquetting machine, briquettes.
