CFD modeling for entrained flow gasifiers

In this paper we have described a CFD based modeling tool for entrained flow coal gasifiers. The model contains sub-models to properly model the reaction kinetics of coal gasification at high pressure, high solids loading and slagging walls. Comparisons between values predicted by our CFD model and modeling studies performed by other research groups have shown good agreement. Although the models have been demonstrated for oxygen blown, pressurized systems the same model could be applied to air-blown or atmospheric systems. Future work will focus on using the model to investigate generic improvements for the operation and design of entrained flow gasifiers.
