摘要
采用ＰＤＡ测量系统对四角切圆燃烧锅炉垂直浓淡煤粉燃烧方式下炉内湍流特性进行了实验研究和频谱分析。结果表明，一次风射流由于与上游横向射流的相互作用，在背火侧形成尾迹涡，在向火侧形成剪切涡。
With PDA System the experiment and spectrum analysis on turbulent now had been conducted for vertical bias combustion in tangentially fired furnace. It is showed that being the interaction between primary air and upstream fluid, the shear eddy the the wake are formed on the two sides of the primary air respectively.
