In oxygen-blown IGCC, the gasification efficiency decreases according as oxygen concentration in the gasifying agent (oxidant) decreases. However, there is a possibility that the improvement of the entire plant efficiency and the cost reduction can be achieved because the producing-power of oxygen can be decreased on the other hand. Therefore a quantitative grasp of the influence that the oxygen concentration exerts on the gasification efficiency is expected. The gasification test regarding the oxygen concentration change was carried out using the bench-scale gasification facility in this study. An (Orimulsion)^<TM> was used for the gasification test. As a result, the influence that the oxygen concentration exerts on the gasification efficiency (e. g. the cold gas efficiency, carbon conversion efficiency and the others) was obtained. The thermal efficiency of a simple IGCC system was calculated based on the relationship between the oxygen concentration and the gasification efficiency. In this study, the oxygen ratio to achieve high efficiency at each of concentrations was clarified
