本文作者提出了考虑流化床内气泡运动,颗粒的小尺度随机湍动影响因素在内的流化颗粒传热数学模型,所得计算结果与实验结果甚为吻合。本模型可用于建立沸腾炉燃烧的综合数学模型及沸腾炉的设计计算。
The authors propose a mathematical model for heat transfer of fluidized particles considering the bubble motion in the fluidized bed and the small-scale random turbulence of the particles. The calculated results are in good agreement with the experimental results. The model can be used to establish a comprehensive mathematical model of the boiler combustion and the design and calculation of the boiler.
