以循环流化床传热的颗粒絮团更新理论为基础，建立了一个计算床层与壁面间时均局部传热系数的数学模型。通过将循环流化床床层沿高度分段的方法，构想了颗粒絮团在壁面的形成与运动过程，考虑了床层密度的的轴向分布对时均局部传热系数的影响。模型计算结果与有关试验数据的对比表明该模型基本有效。图３ 参１３ Based on the particle floc update theory of circulating fluidized bed heat transfer, a mathematical model for calculating the local average heat transfer coefficient between the bed and the wall was established. The formation and movement of granular flocs on the wall surface are conceived through the method of segregating the circulating fluidized bed in height. The influence of the axial distribution of bed density on the local average heat transfer coefficient is considered. Comparison between the model calculation results and the relevant experimental data shows that the model is basically effective. Figure 3 reference 13
