Abstract: 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.
