Application of thermoelectric generator in waste heat recovery

This chapter explores the potential of thermoelectric generators (TEGs) in waste heat recovery (WHR), presenting an innovative approach to addressing energy efficiency and environmental challenges. TEGs utilize the Seebeck effect to convert temperature differences into electrical energy, offering a sustainable solution for capturing waste heat from industrial chimneys, automobile exhaust systems, and diesel generators. This chapter examines key factors influencing TEG performance, such as cooling mechanisms, heat transfer methods, and module arrangement, and highlights how chimney inclination and cooling fluid types impact efficiency. Additionally, it emphasizes the environmental and economic benefits of WHR using TEGs, including reduced greenhouse gas emissions and enhanced energy utilization. By integrating advanced materials and innovative designs, TEG technology demonstrates significant promise for transforming waste heat into valuable energy across various industries. This analysis underscores the critical role of TEGs in promoting sustainable energy solutions and mitigating environmental pollution.
