| 概要 |
This study investigates the integration of thermoelectric generators (TEGs) into biomass cookstoves to convert waste heat into electricity, addressing energy poverty and indoor air pollution. The syst...em achieved a maximum power output of 90.1 mW at a 26°C temperature difference and 1.5% system efficiency at 61.6°C. Key challenges included suboptimal cooling and thermal management, which limited performance. Experimental results demonstrated the critical role of load matching, with peak power occurring at 8 Ω external resistance. A quadratic trendline modeled the power-voltage relationship, while scalability analysis projected 840 mW output for a 24-TEG array, sufficient for off-grid applications like LED lighting. Despite inefficiencies in maintaining temperature gradients, the study highlights TEGs' potential for decentralized energy solutions in underserved communities. Future work should optimize cooling systems and modular designs to enhance practicality and performance.続きを見る
