摘    要:本文利用气体示踪法研究燃烧器一、二次风混合扩散特性,对弱旋流(一次风)燃烧器和直流(侧边二次风)燃烧器组成的燃烧器组各股风混合情况进行了详细研究,得出各截面混合物浓度分布规律及混合强度分布规律,分析对燃烧着火的影响,对燃烧器设计参数的选择有指导意义。

关 键 词:燃烧器  混合扩散  气体示踪分析  气体扩散

Abstract:he characteristics of lateral mixing and diffusion between primary air (low-swirl) and secondary air (no-swirl) of the burner with side-located secondary air were studied carefully by gas tracer analysis. The profiles of mixture concentration and mixing indensity at various cross-sections along the axis were achieved. The effects of them on fuel ignition were also discussed. The results are of practical significance for design of the burner.
Keywords:Burner  Air mixing and diffusion  Gas tracer analysis
