Abstract设计了同轴套管式非热等离子体作用于甲烷扩散火焰的燃烧器,研究了非热等离子体影响甲烷扩散火焰的基本现象。通过调节甲烷和空气流量的大小,重点研究了非热等离子体对火焰推举高度的影响以及同轴射流对火焰稳定性的影响。实验研究表明,非热等离子体的存在对甲烷扩散火焰的脱火流量,火焰高度、稳定特性都有很大的影响。非热等离子体中的活性成分具有一定的寿命,当火焰根部距离非热等离子体产生的位置达到或超过活性成分在寿命期内可以移动的距离时,非热等离子对火焰的影响减弱或消失。
Other AbstractA diffusion flame burner consisted of two coaxial tubes is designed and applied to study the effect of non-thermal plasma on methane diffusion flame. The basic phenomenon of the methane diffusion flame under dielectric barrier discharge assistance was observed. By adjusting the flow rate of the methane and air, the lifted height of the methane flame and flame stabilization assisted by non-thermal plasma were studied in detail. Experimental studies have shown that, the presence of non-thermal plasma has a great impact on the critical blow-off mass flow rate, flame lifted height, and flame stability characteristics. The active matters generated by dielectric barrier discharge have a limited life. When the position of the root of the flame is far away from the non-thermal plasma zone or exceeds the moving distance of the active matters in the life period, the effect of non-thermal plasma on methane diffusion flame will weaken or even disappear.
