| contents | The demand for sustainable energy has intensified research into biomass torrefaction as an alternative to fossil fuels. This study focuses on the design, development and performance evaluation of a torrefaction machine optimized for processing low density polyethylene (LDPE) biomass composites at 250°C and 300°C for 60 minutes. Key design parameters, including shaft speed, conveyor mechanisms and heat distribution were optimized to enhance efficiency. The effects of torrefaction on the thermal, mechanical and flammability properties of four rice husk to polymer formulations in percentage [A(80/20), B(60/40), C(40/60) and D(20/80)] respectively were analyzed. Physico-thermal properties such as moisture content (MC), volatile matter content (VMC), fixed carbon content (FCC), ash content, calorific value (CV) and flammability characteristics were evaluated. The mechanical properties that were assessed are hardness, tensile strength, impact resistance and compression yield strength (CYST). Results indicate that increasing polymer content enhances FCC, CV (8,539.45 Kcal/kg), burn duration (330s), hardness and CYST (6.5872), while reducing MC and VMC. Sample D containing 20% rice husk & 80% polymer which exhibited the highest energy density and structural integrity is ideal for high-energy and load-bearing applications. Whereas Sample A containing 80% rice husk & 20% polymer is suitable for quick combustion applications because of its rapid ignition of 3s at 300°C. The results from polymer-rich LDPE-biomass composites will be useful for industrial, metallurgical and energy applications. |
