Early practical use of extra heavy oil gasification combined power generation plant (IGCC) is expected from the viewpoint of energy security and environmental protection. It is important to support a reasonable design, and to establish the operation index for highly effective achievement for the practical use of the gasifier. The numerical simulation technology will be useful very much for a reasonable design of the gasifier. However, the grasp and the modeling of the phenomenon in the gasifier are indispensable to the numerical analysis technology. For instance, it is elucidation of the partial oxidation reaction process of coke which exerts a large influence on the gasification efficiency, and elucidation of the mechanism of the coking phenomena which becomes an operation trouble. Then, the gasifier for the phenomenon elucidation in the furnace was developed as a tool to support the design and the operation of the actual gasifier strongly. Using this gasifier, coke and the gas under the reaction are sampled, and the distribution characteristic of a gasification reaction is understood. In the same condition, an indispensable heat flux distribution to the numerical analysis is measured. Planned function of gasifier was confirmed, and development of gasifier for research was achieved. In this report, the design and the operation result of the gasifier are described.
