中文摘要	基于颗粒动力学两相流方法,建立了裤衩腿循环流化床锅炉二维CFD数值计算模型,研究了总物料量和布风板阻力特性对翻床趋势的影响.结果表明:炉膛总物料量越大,平均物料交换率越大,越容易翻床;布风板阻力系数越大,平均物料交换率越小,越不容易翻床;正负反馈机理可以合理解释物料量和布风板阻力特性对翻床的影响;布风板压降和物料压降比是评价裤衩腿循环流化床锅炉自平衡能力的重要参数.; Based on two-phase flow granular dynamics,a two-dimensional CFD numerical model was developed to investigate the impacts of bed inventory and air distributor resistance on the bed inventory overturn process in circulating fluidized bed with pant-legs.Results show that with the rise of bed inventory,the lateral solid flow rate rises,resulting in increased possibility of bed inventory overturn;whereas with the rise of air distributor resistance coefficient,the lateral solid flow rate drops,resulting in reduced possibility of bed inventory overturn.These phenomena can be explained by the mechanism of positive and negative feedback.The pressure drop ratio of air distributor and bed inventory may serve as an important parameter to evaluate the self-balance ability of furnace with pant-legs.
