蒸氣脈衝式史特靈引擎之可行性研究

本研究主要在探討史特靈引擎中，以回收其他機具所產生之廢氣蒸代替原有高壓稀有氣體成為工作流體的可行性。在全球暖化日益嚴重的今日，節能減碳並開發替代性能源成為重要的課題。史特靈引擎有著高工作效率的特性，但一般高效率之史特靈引擎常以高壓氦氣為工作流體，在工作條件以及生產技術上有著許多限制。蒸氣脈衝式史特靈引擎優點在於可回收前端機具所產生之低壓廢棄蒸氣，再加入少量熱源即可以史特循環之高效率產生能量。同時因為蒸氣不斷排出，可達到冷卻史特靈引擎冷端的效果，大幅簡化史特靈引擎內冷卻器構造，降低史特靈引擎在生產技術上的限制，進而增加史特靈引擎之泛用性。

This research focuses on the feasibility of reuse waste steam which exhausted by steam useing equipment. In the growing global warming, reduce carbon emissions and develop alternative energy sources has become an important issue. High-efficiency Stirling engines often use high-pressure helium as the working fluid which limited the working conditions and production process.The benefit of Pulse Steam Stirling Engine (PSSE) is able to reuse low-pressure west steam generated by front-end equipment like 5MW steam turbine.It only takes a few extra energy working in Stirling-cycle to out put more electric power,and the exhausted steam will coolen the cold end,the cooler structure of Stirling Engine could be simplify by the way.It will increased the application of Stirling engines.
