鐵礦燒結製程為煉鐵製程中重要的步驟之一，此前製程對於焦煤炭之消耗相當高，如何有效提升燒結製程製之效率，對於鋼鐵廠降低碳排放量有相當之幫助。而鐵礦燒結製程中包括燃燒反應、物質的相變化以及鐵礦燒結料層中之熱傳與質傳反應。
本研究主要為改善鐵礦燒結製程中之尾氣循環系統以及建立全尺寸之鐵礦燒結製程模型，首先以二維尾氣循環模型去分析，初步分析尾氣循環系統洩漏之問題，再進一步以三維模型模擬尾氣循環系統中之三維效應，改善尾氣循環以及解決鐵礦燒結尾氣循環系統之洩漏問題。
本文也建立了完整之全尺寸鐵礦燒結製程模型，可獲得尾部風箱的流量、溫度及主要氣體成分，其模擬結果與現場量測之趨勢相符，可提供燒結製程操作及診斷的參考。

Iron ore sintering process is one of the important processes in iron making industry, this preprocess has a mass coke consumption. It is advantageous to reduce the carbon dioxide emissions by improving the efficiency of the iron ore sintering process. Iron ore sintering include the combustion reaction, phase change, heat and mass transfer in Iron ore sinter bed.
This study mainly improves the flue gas circulation system in iron ore sintering process, by developing the flue gas circulation model and the full scale three dimensional iron ore sintering model. First, we analyze the two dimensional flue gas circulation model, preliminarily discuss the leaking problem of the FGC system, furthermore, discuss the three dimensional effect in three dimensional flue gas circulation model in order to improve and solve the leaking problem of the iron ore sintering process with FGC system. Second, we build the full scale three dimensional iron ore sintering model which consider the conservation equation of mass, momentum, energy and species, including the water evaporation and condensation within the fine coke combustion heat release.
