論文名稱: 合流化床與史特靈引擎之熱電聯產系統設計與優化 / Design and optimization of combined heat power system incorporating with fluidized bed and Stirling engine
中文摘要:
本研究旨在提升整合流化床生質燃料燃燒器與Stirling引擎的熱電共生（CHP）系統之效能與可靠度，並特別著重確保Stirling引擎、水盤加熱端與燃燒器的穩定操作。實驗將Stirling引擎置於燃燒器上方並與出口連結，生質進料率調整於9.5至17 g/min，維持50至60 L/min的穩定進氣，並以田口法設計九組條件，針對流化床操作區域、材料溫度與出口溫度進行測試。煙氣分析（O2、CO2、CO、NOx）顯示最佳化後系統能降低有害排放，同時維持對引擎足夠的熱傳。結果證明此整合方案可行，也驗證田口法有助於找出穩健的操作條件。
英文摘要:
This thesis improves the performance and reliability of a combined heat and power (CHP) system that integrates a fluidized bed biofuel combustor with a Stirling engine, with emphasis on stable operation of the engine, the heated end of the water tray, and the combustor. The Stirling engine is mounted above the combustor and linked to its outlet. Biomass feed rate was varied between 9.5 and 17 g/min at a steady airflow of 50 to 60 L/min, and the Taguchi method defined nine experimental conditions varying fluidized bed operating area, material temperature, and outlet temperature. Flue gas analysis (O2, CO2, CO, NOx) showed that the optimized setup reduces harmful emissions while maintaining sufficient heat transfer to the engine. The results demonstrate the feasibility of this CHP concept and the value of the Taguchi method for finding robust operating conditions.
