流化床燃烧脱硫模型及速度场模拟的研究

在流化床燃烧脱硫的基础上,分析流化床燃烧脱硫的基本数学模型,同时采用FLU-ENT流体力学分析软件对流化床内的速度场进行了分析和数值模拟。最后得出随着高度的增加速度沿流化床径向的分布是越来越均匀的,在-26～26mm的范围内速度较为均一稳定的最佳条件。 The paper studied the basic mathematical model based on desulfurization in fluidized bed combustion. With FLUENT Fluid Dynamics analysis software,velocity field in fluidized bed was analyzed and numerical simulations were performed.In the last of this paper,we get the optimum condition. It is that as the increase of high,the radial distribution of velocity along fluidized bed was more and more homogeneous,the velocity was rather uniform and stabilized between-26～26mm
