At the exhaust gas dilution condition, the burning duration is extended and the flame speed drops faster at high initial pressure than at low one.
在废气稀释情况下，燃烧时间延长，在高初始燃烧压力时，火焰传播速度下降更明显。

It has shown that adopting revolving air flow and adjusting the flame length by changing the strength of revolving for lowpressure oil burners is feasible.
结果表明：采用旋转气流及用改变旋流强度的方法来调节低压油烧嘴的火焰长度是切实可行的。

Aiming at the facts of low temperature, rare oxygen and low-pressure, ameliorates phenomena of burner igniting difficulty , unsteady flame and incomplete burning by improving on burner's parts.
