重質油氣化複合循環發電系統（IGCC）在改善熱效率、減少溫室氣體排放、以及燃料的多選擇性上之實際使用一直被人們寄予厚望。於是本論文研究主題為探討乳化重油ORIMULSION，其在噴流床式氣化爐中之氣化特性。初步先假設進口燃料為ORIMULSION高溫熱解(Pyrolysis)後之主要物質：CH4、H2O、CO、CO2、H2及C。目的在觀察及比較在經過整體氣化反應後，爐內溫度分佈及出口合成氣（Syngas）組成。在假設碳為氣態以及固定燃料供給量下，我們分別使用不同供氧量，紊流模式，壁面溫度及操作壓力為操作條件。研究發現，若增加氧化劑，會導致H2及CO產量減少，CO2增加，且對H2O影響不大。而使用DSM紊流模式下，H2O產量會有明顯的增加，且會計算出較慢的紊流混合速率。同時增加壁面溫度對合成氣產量影響不顯著。而操作壓力在1.8MPa下就可以達到預計的效果。

　　The practical use of Integrated extra heavy oil Gasification Combined Cycle (IGCC) power generation is expected from the viewpoints of the improvement of thermal efficiency, the decrease in emission of greenhouse gases, the fuel diversification, and the cost decrease, etc. The theme of studying in this thesis lies in probing into the emulsified heavy oil named ORIMULSION gasification characteristic in the entrained-flow gasifier. Tentatively, suppose the fuel imported as ORIMULSION composition after pyrolysis: CH4、H2O、CO、CO2、H2 and C. The purpose lies in observing and comparing the distribution of temperature in the chamber and the composition of syngas exported after the global gasification reactions finish. Furthermore, suppose gaseous carbon and fixed fuel supply, respectively we use different oxygen supply , turbulence model , wall temperature and operation pressure as operation conditions. The result of study shows: When increasing the oxidant supply, it will cause the reduction of H2 and CO and increase of CO2 in the exit, and it also have a little effect on H2O. If DSM turbulence model is enabled being used for calculating, then H2O will increase in a large amount obviously and calculate out slower turbulence mixing speed. The way to increase wall temperature does not have obvious influence on syngas exported at the same time. And operation pressure can get the ideal result of estimating at 1.8MPa.
