Abstract

The article focuses on optimizing waste heat recovery (WHR) in a stationary dual-fuel diesel engine by integrating thermoelectric generation (TEG) with heat pipes. The engine operates using waste cooking oil methyl ester as pilot fuel and biogas as induction fuel, with experiments conducted at 1, 2, and 3 kW loads. Results show that incorporating heat pipes as heat sinks significantly increases the temperature difference (DT) across thermoelectric modules, enhancing heat dissipation from the cold side and thereby improving electrical power output and conversion efficiency—achieving up to 6.1 W power and 2.9% efficiency at 75% engine load. The study highlights the importance of effective thermal management via heat pipes to maximize TEG performance in waste heat recovery applications, particularly for dual-fuel engines using renewable fuels.
