摘要
本文研究偏心射流的倾斜角对燃烧效率、贫油吹熄特性和出口温度场的影响.给出了同一燃烧室在轴对称进气条件下的相应特性.结果表明,偏心进气能明显扩大贫油吹熄范围,提高燃烧效率.在试验的角度范围内,适当加大偏心射流的倾角是有利的.
The effect of the air jet with oblique angle on combustion efficiency, fuel-lean limit and temperature profile at the combustor exit was investigated experimentally. A combustor with an axisymmetric air jet was also investigated for making a comparison. Results show that fuel-lean limit and combustion efficiency can be improved evidently in the combustor with an. oblique air jet, and that the combustor performance with jet oblique angle of 15° is much better than that with jet oblique angle of 10°.
