Computer simulation has been proven to provide a good understanding of engineering phenomenon. This work presents numerical simulation results on secondary air jet penetration into a dense phase of a three-dimensional fluidized bed at a commercial scale. Initial model as a reference and four modified models which are called as case A, B, C, and D were created by modifying the angle of secondary air. Evaluation of combustion process is based on mass fraction distribution of HO and CO at center line of the furnace. Generally, modified geometry improves the performance of furnace compared to reference. We also present data of total energy and temperature to get a comprehensive insight of the furnace performance. The simulation results can be used as a consideration to improve the efficiency of steam power plants by adjusting the direction of secondary air flow.
计算机模拟已被证明能很好地理解工程现象。这项工作展示了在商业规模下二次空气射流穿透三维流化床密相区的数值模拟结果。通过修改二次空气的角度创建了作为参考的初始模型以及四个被称为案例A、B、C和D的修改模型。燃烧过程的评估基于炉膛中心线处HO和CO的质量分数分布。一般来说，与参考模型相比，修改后的几何形状提高了炉膛性能。我们还给出了总能量和温度数据，以全面了解炉膛性能。模拟结果可作为通过调整二次空气流动方向来提高蒸汽发电厂效率的参考。
