摘要

經濟部能源局繼97年7月15日推動國內之車用柴油全面添加1％生質柴油(簡稱B1)措施，目前更進一步於今(99)年6月15日起加倍提高至2％(簡稱B2)，不難看出生質能對未來在替代能源及環境提升方面的重要性。
使用微型渦輪機結合熱回收系統作為分散式發電機組之動力源為目前主流，傳統渦輪機組勢必朝向更高之能源使用效率或結合再生能源等方向發展，因此本研究使用一具有熱回收系統之微型渦輪發電，做為測試載具，探討微型渦輪機使用生質柴油之可行性與性能變化。本研究可分為實驗測試與性能分析二部分，實驗測試方面使用濃度10％～30％之生質柴油與石化柴油混合，利用訊號擷取系統對引擎參數及排氣檢測方面進行紀錄。性能分析部份則使用GasTurb渦輪引擎性能分析程式，將各組測試所得結果輸入其中進行計算，可計算各組件效率與系統總效率，最後與測試結果比對，預測B100的對引擎性能的影響。
最後將針對不同濃度實驗結果加以分析比較，以歸納出不同的生質柴油濃度對於性能與排出氣體之影響，建立一套微型渦輪機使用生質柴油的性能及排氣資料庫，以協助未來為在微型渦輪引擎的設計及產品的開發，提供國內相關研究單位與廠商作為參考。

The Bureau of Energy under the Ministry of Economic Affairs proposed a policy to promote the addition of 1% biodiesel (called B1) into diesel in domestic utilization in july 15, 2008 followed by the addition of 2% biodiesel (called B2) by june 15, 2010. It is important to use biomass as an alternative energy to protect the environment in the future.
Nowadays microturbine combined heat recovery systems have become the mainstream trend in distributed power generation. The conventional microturbines have increased efficiency and utilization of renewable fuel. Therefore, the objective of this thesis is to test the feasibility of integration of microturbine with a heat recovery system and performance of the system when fueled by a mixture of biodiesel and petrodiesel. This research can be divided into two parts: the experimental part and the performance analysis. In the experimental part, the microturbine was fuel with mixture of biodiesel and petrodiesel with volumetric concentration from 10% to 30%. The engine parameters and exhaust emissions were recorded by a Data Acquisition Recorder. In order to analyze the performance of the system, GasTurb, a turbine engine performance analysis program, was employed to calculate various system components efficiency and overall efficiency by using recorded data. The comparison of the experimental result and the simulation were used to predict the effects of fueling engine by 100% biodiesel on the system performance.
Overall, this project were concluded by preparing a performance and exhaust emissions database to assist companies and research groups to design microturbine fueled by biodiesel with different concentrations.
