CRIEPI is developing a high thermal efficiency integrated coal gasification combined cycle power generation system. The thermal efficiency of the system is enhanced by an active utilization of steam injection into a gasifier, which is expected to promote the steam gasification. The previous survey research by CRIEPI showed the possibility of a higher cold gas efficiency and the expected problems of the system. In this report, a numerical simulation was conducted to reproduce the gasification tests in the 3t/d bench scale coal gasifier that investigated the effect of steam injection experimentally. The simulation revealed that the gasification reaction area in the redactor varied significantly. Furthermore, it showed a suppression of CO2 gasification, promotion of H2O gasification, and promotion of total carbon consumption by gasification reaction in the reductor.
