Oxy-Fuel IGCC system is expected to be a promising power generation system achieving both high thermal efficiency and low carbon emission. CO2 concentration in a gasifier becomes higher than that in a conventional gasifier, hence basification behavior in a gasifier under high CO2 concentration should be clarified prior to specific gasifier design. In this study, the effect of operation condition on the gasification behavior in the Oxy-Fuel IGCC condition was numerically investigated. Results showed that although coal gasification is occurred both combustor and reductor, gasification reaction in combustor is rather dominate. Moreover, Higher R/T condition increased coal gasifier performance. This is due to the fact that heat generated partial oxidation is effectively used by coal gasification without heat loss from the gasifier wall in higher R/T case.
