“…At this moisture content, the briquettes are strong and free of cracks and the compacting process is preferential [8; 9]. It is known that briquette densities were of a consistently higher value, when the biomass samples were compressed at a lower moisture level [10], therefore the experiments were carried out on materials with a mean moisture content of 8.7 %.…”

Removal of common reeds (Phragmites Australis) from the lake shorelines is also the lake restoration action and improving the water quality. The use of common reed as biomass for the production of solid fuels can significantly reduce the use of fossil fuels. Common reed is a freely available resource in the overgrown lakes of Latvia. Common reed solid biofuel production technology after grinding provides briquetting to required density. The purpose of the work is theoretically to determine the resistance characteristic for the pressing mechanism modelling. In laboratory experiments briquettes were produced from grinded common reed particles. The main tasks of the laboratory experiments were determination of the compacting force-displacement characteristics for compacting of different size common reed particles. On the basis of the results of the compacting experiments non-linear particle compression resistance characteristic with Mathcad programme was developed. The mechanical model contains a spring incorporated in the rhomboid mechanism. Comparing the results of experiments and modelling the maximal difference 4.96 % (screen size 1.5 mm), 1.98 % (screen size 6 mm), 8.45 % (screen size 12 mm) and 6.94 % (screen size 20 mm) was determined.

“…In spite of the fact that moisture has an important effect in the densification and durability of the final briquettes [43,44], this parameter has not been modified in order to not increase the briquetting process costs, so the values of moisture of the used materials are those shown in Table 1. …”

Abstract:In this study, the physical properties of briquettes produced from two different biomass feedstocks (sawdust and date palm trunk) and different plastic wastes were investigated, without using any external binding agent. The biomass feedstocks were blended with different ratios of two WEEE plastics (halogen-free wire and print circuit boards (PCB)) and automotive shredder residues (ASR). The briquettes production is studied at different waste proportions (10-30%), pressures (22-67 MPa) and temperatures (room-130 ˚C). Physical properties as density and durability rating were measured, usually increasing with temperature. Palm trunk gave better results than sawdust in most cases, due to its moisture content and the extremely fine particles that are easily obtained.

“…The greatest number of 65% was in case of the fraction particle above 3.15 mm. Dimensional variability of grains in the mixture should allow the best possible filling of empty spaces between the biggest dimensional particles of grains by fine and dust fractions (Guo et al, 2016, Wróbel et al, 2013. Willow as a biomass addition supplements the lacking fine fraction in the RDF-biomass thus it may constitute some kind of a binder and filler which combines bigger RDF particles in the briquetting process (Fig.…”

The impact of biomass addition to the RDF oversize fraction on quality parameters obtained from this blend of briquettes produced under semi-industrial conditions was analysed. For the purposes related to the experiment four RDF mixtures with fragmented biomass of common willow Salix viminalis L., differing only with percentage participation of base elements, were prepared. The briquetting process was performed with the use of a semi-industrial briquetting machine at the determined compaction pressure of 47 MPa and a diameter of a sleeve (and a briquette at the same time) of 50 mm. Selected quality parameters of produced briquettes were determined, i.e. density, mechanical strength DU and compression strength. The best parameters were obtained for briquettes produced from the blend with a 50% share of willow (ρ=843.9 kg·m -3 , DU=86.1%, R c =0.46 MPa). The lowest parameters were in case of briquettes without biomass addition. Statistical analysis of research results indicates that biomass additions to RDF significantly affect the improvement of quality parameters of the obtained briquettes.
