“…Similarly, for all briquettes, the FCR increased binder concentration increases. This implied that high binder concentrations had a substantial effect on briquette performance in briquetting, which is consistent with the findings of Nikiema et al [41] on the optimization of corncob briquettes.…”

Briquettes from raw biomass exhibit smokiness and emits irritant gases. Technical solutions were found in feedstock pretreatment and appropriate binder selection, which this study investigated. Torrefaction and fermentation pretreatments and used printing paper (UPP), newsprint (Np), and clay (C) were selected for experimentation. Samples of Gmelina arborea sawdust (GaS) collected from sawmills were characterized using the ASTM standards. Hollow briquettes were produced at 10:90%, 20:80%, 30:70%, 40:60%, and 50:50% feedstock/binder mixes. Data were analyzed using descriptive statistics and ANOVA at α0.05. Results showed that torrefaction yield increased with torrefaction time, particle density increased with fermentation time but decreased with torrefaction time. Proximate values significantly differ for torrefied and fermented GaS, while heating value (HHV) increased with residence for torrefied and fermented briquettes. Torrefied UPP briquettes produced non-luminous flame and less smoke. Clay briquettes, however, had charred combustion. Fuel consumption increased with binder concentration but decreased with an increase in residence time.

Background and Objective: Technical complexity, power source, cost, and product value are some challenging considerations in briquetting. Most of the available briquetting options are not sustainable due to these challenges, therefore, improved intermediate technology options requiring low energy consumption, high-energy product and acceptable combustion characteristics to meet these challenges are justified by developing a multiple-piston hydraulic briquetting press (HBP) and characterizing the briquettes produced from Gmelina arborea sawdust and newsprint binder. Materials and Methods: Sorted Gmelina arborea sawdust was mixed with pulped newsprint fibers in 5 ratios 10, 20, 30, 40 and 50%, respectively, to produce briquettes. The briquettes were characterized using American Society for Testing and Materials (ASTM), British Standard (BS), and International Standards Organization (ISO) test procedures to determine briquette characteristics. Results: The machine output capacity was 96 briquettes/hour, with low production cost (NGN40, 000.00). The briquettes produced are structurally stable with dimensions: 15.00 mm internal hole, 80.00 mm external diameter, and 60.00 mm height. Low binder briquettes (90:10% wt/wt) are fragile and brittle, while higher binder briquettes are strong and durable. Binder concentration positively improves the combustion characteristics, while the time spent cooking 1 kg of yam is not significantly different for rice. The briquettes thermal efficiency in stove was significantly affected by binder concentration and stove characteristics. Conclusion: The outcomes of this study including high machine output capacity, briquettes' stability, luminous flame and reduced smokiness showed positive quality contributions to densification study and hence, suitability for domestic heating.

“…The results of the drop test show that the higher the temperature in the torefaction process, the lower the friability of the briquettes. This is due to a more stable density level [38], [39]. However, in contrast to the apparent density analysis, it shows that the higher the torrefaction temperature, the lower the briquette density.…”

Indonesia is a country which has rich biological diversity. King grass (Pennisetum Purpupoides) is one of biological species which easily grow but has not yet been optimally used. This study examined the physical, mechanical, and thermal properties of biobriquettes produced from king grass which has been torrefied at temperatures of 150˚C, 175˚C and 200˚C. Prior to torrefaction process, fresh king grass was chopped to a size <3 cm, dried under the sun for five days, and then put into the torrefaction reactor with a residence time of 45 minutes. The resulting solid product, i.e. biochar was then pulverized and sieved to a particle size of 40 mesh, then mixed with 20% wt binder and stirred manually to reach homogeneous. Subsequently, a purposely made press machine was used to produce briquette at a pressure of 150 kg/cm 2 followed by drying the product under the sun for three days. The briquette characterization employed several techniques including thermogravimetry analysis (TGA), differential scanning calorimetry (DSC), bomb calorimeter, and mechanical testing. The results showed that the calorific value of king grass increased from 3747 cal/g to 4346 cal/g after the torrefaction process at a temperature of 175˚C. The results of the proximate test showed that the fixed carbon content increased from 4.76% to 25.75% after the torrefaction process at a temperature of 175˚C. In terms of mechanical properties, it is known that the torrefaction process of king grass has significantly improved the friability, density and size stability. Overall, this study has succeeded in revealing the potential use of briquette products made from king grass as alternative fuel for co-firing at steam power plant.
