摘　　要：层燃垃圾焚烧炉本身结构复杂,影响因素较多,所以原型及模型的冷、热态实验所消耗的人力、物力都较大。随着计算传热学、计算流体力学的发展,已经能够对比较复杂的炉内速度场进行数值模拟,并可获得满意的结果。对垃圾焚烧炉在8种不同工况的炉内速度场分布进行了数值模拟仿真,根据其流场的分析结果得到炉拱的最佳无量纲设计准则为:H/L=0.333,h/L=0.12,前拱角度为45°。The laminar Combustion Municipal solid waste incinerator has a complicated structure and many influencing factors,so the cold and hot state experiments of the prototype and model consume large labor and material resources.It has been able to simulate the more complex velocity field in the furnace with the development of computational heat transfer and computational fluid dynamics,and obtain satisfactory results.In this paper,the velocity field in furnace of Municipal solid waste incinerator under 8 different working conditions is simulated,and according to the analysis of the flow field,the best dimensionless criterion of the furnace arch is:H/L=0.333,h/L=0.12,the angle of the front arch is 45°.
