The optimum jet distance for jet pressure pulsation was about 7-14 times of nozzle exitdiameter.
实验还表明,自激振荡脉冲喷嘴射流存在最优喷距,最优喷距的大小为喷嘴出口直径的7~14倍。

Internal diameter nozzle and nozzle exitdiameter should to be a certain degree of matching relations.
喷嘴内腔孔径应和喷嘴出口口径有一定的匹配关系。

The diameter of actual tangent circle is an important parameter for safety of boiler, the residual rotation is the key factor of flue gas temperature deviation at furnace exit.
