摘　　要：针对某大型工业四通道煤粉燃烧器进行了研究,通过使用UG和Fluent软件分别对该燃烧器进行三维建模和结构化网格划分。采用Realizableκ-ε湍流模型和Simple算法,研究了该燃烧器内流场的变化并对其进行数值分析与仿真,获得了与实际情况相符的流场分布图。结果证明了仿真结果的可靠性和采用Realizableκ-ε模型的可行性。A burner is important for producing cement.Its performance has great impact on the cost and quality of the cement it produces.This paper uses the softwares of UG and Fluent to establish the 3-dimensional model of the 4-channel coal burner and generate its structural mesh.It also uses the realizable κ-ε turbulence model and the simple algorithm to study and simulate the changes in the inner flow field of the 4-channel coal burner,thus obtaining the contours of the flow field which agree with the actual conditions.The realizable κ-ε model is feasible and the simulation results are reliable.This study sheds some light on improving the structure of a 4-channel coal burner and optimizing its parameters.
