Abstract
Densification of agroforestry biomass for energy production has positively impacted the energy sector across the globe. Wood fuel consumption has led to deforestation and degradation. Recently, much has been discussed on biomass briquetting technologies and their influence. However, knowledge about appropriate technique for briquetting to achieve high-quality briquettes is yet to be explored. Thus, efforts were made to critically evaluate briquetting techniques on briquettes’ combustion performance properties. The Water Boiling Test was used in the determination of various parameters. High (screw press); and low (drum agglomerator and hand making) pressure briquetting techniques were distinctly different in ignition time (minutes), time to boil (minutes) burning rate (g/min), specific fuel consumption (g/ml) and power output (kW) values as (1.3,1.0,0.9; 14, 12, 11: 0.8, 1.1, 1.3; 0.11, 0.13, 0.15; and 1.8, 1.4, 0.75). Briquetting technology, based on pressure, is thus a factor that influence performance properties of briquettes. This knowledge is therefore useful when converting waste biomass into briquettes as alternate energy source towards realization of Sustainable Development Goal #7 on affordable and clean energy.
