Coal gasification simulators were developed to analyze and predict thermal, chemical, and physical phenomena in pressurized entrained-flow coal gasifiers. The simulator was based on two computational fluid dynamic (CFD) codes: the "RESORT (REvolutionary Software Orchestrated Reactions in Turbulent flow)" that originated from the BRAIN-C project and the commercial code "FLUENT". The devolatilization model, char gasification reaction models, and ash particle deposition model were modified with the two CFD codes to make accurate predictions about slag-tap coal gasifiers. These solutions were then compared with the data measured at 2 and 50 ton/day entrained flow coal gasification pilot plants. The simulator could predict both temperature profiles and ash deposition profiles fairly accurately. These simulation software and the tutorial manuals had already been provided to many of the project members. Now, these gasification simulators are being used in Japanese national coal gasification project. The entrained flow coal gasification simulator would contribute to reduce technical and financial burden in developing and commercializing the coal gasification processes.
