Abstract：In order to improve the gas flow field in the bottom region of a eirculating fluidized bed desulfurization reactor with nonuniformity generated by its inlet configuration which con-sisted of bend pxpe and venturi tube,a numerical simulation for gas flow field of desulfurization reactor was performed using a RNG_(κ-ε)turbulent model.The influence mecha nism of inlet con-figuration on gas flow field in the desulfurization tower was discussed,and some attemDts were also performed to optimize current inlet configuration.The results show that the RNG_(κ-ε)tur-bulent model can simulate the turbulent flow of inlet configuration well.Due to bend pipe and venturl tube,the gas flow field in the desulfurization tower is badly affected by current inlet configuration,while the circulating feed inlet affects little on it.Among three modification methods,modified guide vanes is found to successfully optimize the gas flow profiles in the desulfurization tower well while the bed pressure drop caused by it is small.
