摘要

盤元進入冷卻床時的溫度仍高於700℃，有大量的輻射熱散失到環境中，有鑑於此，本研究將熱輻射熱電發電系統裝置在盤元冷卻床上，為國內首座裝置於鋼鐵業冷卻床回收輻射熱來發電的系統。測試結果顯示，本系統回收輻射熱後，發電量最高可達320 W以上。本研究之成果可做為熱電發電技術擴展應用至其他具有大量輻射熱的產業上之參考。

For steel industry, the coil's temperature into coil cooling bed was higher than 700℃, so a lot of thermal radiation lost to environment. Because of this, this study built the thermoelectric power generation system on coil cooling bed to recover thermal radiation. It is the first time to recover thermal radiation of coil cooling bed to generate power in Taiwan's steel industry. The results of performance tests revealed that the thermoelectric power generation system could recover thermal radiation to generate 320 W power above. The results of this research can be used as a reference for expanding the application of thermoelectric power generation technology to other industries with a large amount of radiant heat.
