Abstract
This study aims to investigate the carbonization process to improve the thermal efficiency of sawdust fuel briquettes using a cold screw compaction technique. The briquettes were produced using a single-phase electric motor (3 HP) operating at a screw speed of 210 RPM. Molasses was used as a binder, mixed with water in two proportions (60:40 and 70:30), and combined with biomass at various ratios: 100:0, 95:5, 90:10, 85:15, and 80:20. The physical properties evaluated included heating value, amount of heat , and thermal efficiency. The experimental results revealed that the carbonization process significantly increased the calorific value of the briquettes due to the higher carbon content, albeit with a reduction in overall yield. Among the tested conditions, the briquettes produced with an 80:20 biomass-to-binder ratio and subjected to carbonization exhibited the highest performance, yielding an energy content of 22.46 kJ, a calorific value of 19.80 MJ/kg, and a thermal efficiency of 72.44%. These findings suggest that carbonization can effectively enhance the fuel properties of sawdust briquettes, with the 80:20 ratio offering an optimal balance between energy performance and material utilization.
