摘要：以内回油机械雾化燃油燃烧器为例进行雾化与燃烧仿真研究,研究配风对雾化锥的影响。结果表明:喷油口孔径增大时,雾化锥角增大;喷油口孔长度减小,雾化锥角增大。直流风量增大时,雾化锥被拉长,火焰变得细长;直流风量减小,雾化锥的长度被缩短,火焰变得粗短。当配风使得过氧量在2%附近时,最高温度和平均温度的值取得最大,热效率最高,因此确定合理的配风是过氧量的2%～4%。

Abstract：The atomization and combustion simulation were researched based on the example of oil combustor， and the effects of winding quantity on the atomizing cone were studied. The results showed that when the aperture of atomizing nozzle increased， the atomizing cone angle also increased. When the length of the orifice of atomizing nozzle diminished， the atomizing cone angle enlarged. When the quantity of direct wind increased， the atomizing cone was elongated， and the flame became slight. While the quantity of direct wind decreased， the length of atomizing cone was shortened， and the flame became blunt. As the winding quantity made the oxygen supplied about 2% more than theoretical value that the combustion needed， both of the maximum temperature and mean temperature went up to the highest peak. That meant that the best thermal efficiency appeared. So the ideal winding quantity was the case of 2%~4% oxygen over supplied.
