基于计算粒子流体动力学（CPFD），采用欧拉拉格朗日法建立了三维可压缩循环流化床（CFB）燃烧数学模型。该模型考虑了传热传质和化学反应。此外，通过改变模拟中的运行参数，得到了油页岩固废与玉米秸秆颗粒在循环流化床燃烧过程中的温度分布、气体成分分布以及化学反应速率的变化。将模型计算得到的温度分布与实验结果进行了比较。结果表明，数值模拟结果与实验结果吻合较好。该研究为今后流化床反应器的优化设计奠定了基础。(C)2017爱思唯尔有限公司版权所有
In the present study, based upon the Computational Particle Fluid Dynamics (CPFD), the Euler Lagrange method has been used to establish a three-dimensional compressible Circulating Fluidized Bed (CFB) combustion mathematical model. The model considers the heat and mass transfer, and the chemical reactions. In addition, by varying the operating parameters in the simulation, the temperature distribution, gas composition distribution, change in the rate of chemical reaction of the oil shale retorting solid waste with cornstalk particles during CFB combustion were obtained. The temperature distribution obtained by the model was compared with the experimental results. The results show that the numerical simulation results agreed well with the experimental results. The study forms the basis for a better design of fluidized bed reactors in future. (C) 2017 Elsevier Ltd. All rights reserved.
