“…The volume of the selected pellets and briquettes was estimated using the buoyancy method in liquid. This method has been shown to have a low variability [13,14]. The method is based on the Archimedes principle; the pellet sample is weighed in air and in a liquid.…”

Different methods for the determination of the mechanical durability (DU) of pellets and briquettes were compared by international round robin tests including different laboratories. The DUs of five briquette and 26 pellet types were determined. For briquettes, different rotation numbers of a prototype tumbler and a calculated DU index are compared. For pellets testing, the study compares two standard methods, a tumbling device according to ASAE S 269.4, the Lignotester according to Ö NORM M 7135 and a second tumbling method with a prototype tumbler. For the tested methods, the repeatability, the reproducibility and the required minimum number of replications to achieve given accuracy levels were calculated. Additionally, this study evaluates the relation between DU and particle density.The results show for both pellets and briquettes, that the measured DU values and their variability are influenced by the applied method. Moreover, the variability of the results depend on the biofuel itself. For briquettes of DU above 90%, five replications lead to an accuracy of 2%, while 39 replications are needed to achieve an accuracy of 10%, when briquettes of DU below 90% are tested. For pellets, the tumbling device described by the ASAE standard allows to reach acceptable accuracy levels (1%) with a limited number of replications. Finally, for the tested pellets and briquettes no relation between DU and particle density was found. r

“…Since the briquettes obtained presented a cylindrical form, the density determination was made following a stereometric method as that described by Rabier et al [45]. The briquettes dimensions, diameter and height, were measured using a caliper with a precision to 0.01 mm, whereas the weight was measured with a precise mechanical balance (± 0.01 g).…”

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 combustion characteristics of charcoal produced from wood offcuts of some selected tropical wood species (Iroko, Obeche, Oak, Afara, and Mahogany) were evaluated. The woods offcuts were collected from different saw-mills in Ibadan metropolis, Nigeria and were converted into charcoal using a portable steel kiln. Physicalproperties such as density and proximate analysis i.e. percentage moisture content (PMC), percentage volatile matter (PVM), percentage ash content (PAC), percentage fixed carbon (PFC) and heating values (HV), of the produced charcoal were determined using the American Standard Testing Method (ASTM D1102-56). Analysis of wood and production of charcoal were carried out at the Forestry Research Institute of Nigeria Jericho Ibadan, Oyo State while determination of densities and the proximate analysis tests on the charcoal samples were carried out at
