Oxy-Fuel IGCC system is expected to be a promising power generation system achieving both high thermal efficiency and low carbon emission. CO_2 concentration in a gasifier becomes higher than that in a conventional gasifier, hence basification behavior in a gasifier under high CO_2 concentration should be clarified prior to specific gasifier design. In this study, gasification behavior under the Oxy-Fuel IGCC condition was investigated by means of three dimensional numerical simulation. Results showed that numerical result of temperature distribution and gas composition on gasifier outlet are good agreement with experimental data. It was also found that there is a possibility of improving a gasifier performance under the Oxy-Fuel IGCC condition by adequately controlling operation condition.
