CRIEPI and Mitsubishi Heavy Industry, Ltd. have developed a pressurized two-stage entrained flow coal gasifier using a 2T/D bench scale gasifier. This type of gasifier was adopted for the 200T/D pilot plant project. Based on the results from the pilot plant, all Japanese electric power companies decided to construct the demonstration plant using the pressurized two-stage entrained flow type gasifier. Using the experimental data of 2T/D gasifier for 7 types of coal, this report examines gasification characteristics such as cold gas efficiency, per pass carbon conversion efficiency and fixed carbon conversion efficiency. Now, CRIEPI is developing "Supporting Tool to Optimize Design and Operation of Coal Gasifier" that integrates the experimental technique and the numerical analysis technology. To establish this tool, "3 T/D Coal Gasifier for Basic Research" was designed and set up. A lot of special measurement equipment to clarify the discharge characteristic of molten slag and the ash adhesion characteristic to the gasifier wall have been introduced into this gasifier. From the gasification test results with Chinese coal, it was clarified to be able to evaluate the gasification performances in high accuracy.
