基于CFD的燃烧器火盖性能研究

Research on Performance of Burner Cover Based on CFD

前人已有大量关于燃烧器火盖的研究,提出了火孔的大小及测开孔角度对其性能的影响,近年来火孔的设计已经有了很大的改进,出现了槽型孔,方孔,多孔等火孔结构。本文在同一个燃烧器的基础上,分析研究了传统侧面开孔的火盖与新型的多孔直喷火盖的区别,得到了多孔直喷的引射效果更优,火力更加均匀。

The predecessors have a lot of research on the burner fire cover, and proposed the size of the fire hole and the influence of the angle of the opening on its performance. In recent years, the design of the fire hole has been greatly improved, and the groove type hole has appeared. Square hole, porous and other fire hole structure. Based on the same burner, this paper analyzes and studies the difference between the traditional side-opening fire cover and the new type of porous direct-fired fire cover, and the porous direct injection has better ejector effect and more uniform firepower.
