Development and Optimization of a High Efficiency Sawdust Briquette Machine for Sustainable Energy Production

Abstract

The efficiency of agricultural waste briquettes for domestic and
industrial applications hinges on their fuel properties. This research
focused on briquettes created from mahogany and iroko hardwood
residues. These residues were sun-dried and sieved into various
particles size before being composition of the briquettes. The findings
indicate that both types sever as viable biomass fuels, with mahogany
briquettes exhibiting superior attributes compared to iroko. Optimal
results were identified at a particle diameter of 0.85 mm using
mahogany. Yielding a briquette with a density of 0.8390 kg/m.
compaction pressure of 1.4669 N/m, moisture content of 31.39%, and
a calorific value of 28.953 Kj/kg. The optimization process
highlighted a desirability function of 0.4393, underscoring the
effectiveness of the selected parameters.
