將配備有線性發電機的自由活塞型史特靈引擎安裝於小型焚化爐上,兩者匹配程度遠優於汽輪機與小型焚化爐的組合,更能有效率地回收廢熱,產生電力。
本文利用一個熱傳模型來探討安裝在小型焚化爐上之自由活塞型史特靈引擎的效能。藉由改變熱源溫度、熱沈溫度及熱傳係數的變化因子,來估算史特靈引擎的效率及最佳輸出功;此外,由內部不可逆與外部不可逆所造成之影響也列入評估。
本文所呈現的結果,對工程師及設計人員在回收小型焚化爐廢熱方面,提供了很有價值的資訊。
A free-piston Stirling engine integrated with a linear alternator and an incinerator is able to effectively recover the waste energy and generate electrical power.
In this study, a cycle-averaged heat transfer model is employed to investigate the performance of a free-piston Stirling engine installed on an incinerator. With the input of source and sink temperatures and realistic heat transfer coefficients, the efficiency and the optimal power output are estimated, and the effects induced by internal and external irreversibilities are also evaluated.
Results of this study provide valuable information for engineers and designers to recover energy from small-scale incinerators.
