分级着火油燃烧器的冷态实验研究

Experimental Study on Step-Firing Oil Combustor

为了得到油燃烧分级着火的有效配置 ,解决将少量油和空气混合物送入回流区中心的问题 ,设置了带喷孔的中心套筒 ,并进行了一系列冷态试验。试验测定了燃烧器出口流场和喷雾密度分布 ,证明了上述方法的有效性 。

This article presents the measurement of the outlet flow field and spray moisture density under different working conditions.Up till now,the key problem of how to put the oil moisture into the recirculation zone has been solved,and the appropriate value of the main parameters were obtained through the experiments.
