The curve of relationship between flame speeds and the primary air ratio is got, and when primary air ratio is about 0.

在实验中,主要通过调整一次空气系数和引射器喷口的大小,达到稳定燃烧的运行工况。
In experiment, steady operating point of combustion can be obtained mainly by setting primary air factor and the size of spout.

当二次空气的入口温度低于一次空气的露点温度时,一次空气的冷却有可能是一去湿过程。
When the entering temperature of the secondary air is lower than the dewpoint temperature of the primary air, there may be a dehumidifying cooling pro-cess in the primary air passages.
