熱電發電技術應用現況與發展

Recent Development of Thermoelectric Generation Application

摘要


因應現今世界面臨到的石油短缺及環境汙染的問題,人類開創的綠色能源最受矚目的往往是太陽光電、風力發電、潮汐發電、以及地熱發電,但許多工業製程及汽機車引擎產生的廢熱,則是無法有效利用。本論文乃闡述熱電發電系統在各領域的應用方式,以及其目前進展。根據過去的一些研究結果及實際應用顯示出,熱電材料轉換率大部分位於10%以下,而實際組裝成熱電發電系統後,因為有著接合技術以及裝置成本的考量,使得整體系統轉換效率更低。但產業上的利用價值,是建立在轉換出的可利用電總量,以及其在特殊環境時的不可取代性。以Toshiba的草津溫泉發電系統為例,其每天產生的電量可儲存後做為急難時附近地區的備用電力來源。BMW利用汽車排氣管的廢熱回收的電,則可以回充至電瓶內,減少所需的燃油並提高燃油使用效率。而在太空計劃中,放射性同位素熱電發電則是在外星球探險時的必要電力來源。

並列摘要


To solve the problem of petroleum shortage and enviorment pollution, the most popular green energy research is solar energy, wind power generator, and tidal energy, etc. On the other hand, the waste heat emitted by factories and vehicles can not be properly. This paper demonstrates the application and development of thermoelectric generation system in diffierent situation. According to some recent papers, thermoelectric transform rate is about 10%, and the generation system of it is even lower. Althrough it is true, the value of thermoelectric generation is based on the total amount of power, and the irreplaceable in special condition. For instance, the generator in Kusatsu Hot Spring, run by Toshiba Corp., has become a back-up power source in neighbor area. BMW use vehicle waste heat harvest system to enhance fuel efficiency. Space Venturing Program also uses it as an irreplaceable power source when spacecrafts travel to the other planet.
