고온용 폐열회수 열전발전시스템에 관한 실험적 연구

다국어 초록 (Multilingual Abstract)

Only around one-third of energy input is utilized as usable energy in most of fuel operating systems. The remainder of 66% of energy is wasted to atmosphere in the form of waste heat. One possible way to improve the efficiency of such systems is to recover waste heat by using thermoelectric generation systems which can directly convert heat into electricity. In the present study, the thermoelectric generation system operating in temperature higher than 200℃ was constructed to simulate and evaluate the thermoelectric waste heat recovery system. Commercially available thermoelectric modules were attached to a stainless steel duct, and a hot air blower was faced to the duct inlet. By controlling the hot air inlet temperature, open circuit voltage of the thermoelectric generation system was measured. The main feature of this study was to use a high temperature condition up to 200℃ to ensure the reliability of the thermoelectric generation system, especially for the case of diesel vehicles which discharge exhaust gas of as high as around 200~300℃ at the outlet of the catalyst filter.
