双通道旋流煤粉燃烧器空气动力场的试验研究

Experiment on Aerodynamic Flow Field of Dual-vane Swirl Pulverized Coal Burner

对在双通道旋流燃烧器出口加装不同形状的钝体进行了冷态试验研究，比较了不同钝体对旋流燃烧器出口空气动力场的影响，找到了合理的钝体形式。

Through analyzing the cold model experiment of dual－vane swirl pulverized coal burner whose outlet is fixed different bluff object．The shape of bluff object in reason is found out by comparing the effect of different bluff objects on aerodynamic flow field of swirl pulverized coal burner＇s outlet．
