Abstract	The gasification industry has identified improved performance of entrained flow gasifiers as a requirement for Integrated Gasification Combined Cycle (IGCC) power plants to be commercially viable. Recent review papers by [Steigel et al, 2001] and [Holt, 2001a] identified several items that could lead to improved Reliability, Availability and Maintainability of solid fuel gasifiers. Some specific problem spots included fuel injector life, refractory wear, carbon conversion and slag management. Better understanding of how these are impacted by operational changes such as fuel type, slurry content and oxidizer flow would be highly beneficial. Both review papers highlighted the need to make greater use of Computational Fluid Dynamics (CFD) modeling of gasifiers. In the last ten years, CFD modeling has been a key tool in improving the performance of the current fleet of pulverized coal fired electric utility boilers. Likewise, CFD modeling can provide insights into the flow field within the gasifier that will lead to improved performance. An excellent review of recent CFD modeling studies conducted for a wide range of gasifier systems is available in [IEA, 2000].
