摘要

平焰燃烧火焰温度较高

燃烧过程中会产生大量的NO。检测不同烧嘴结构下平焰燃烧的火焰温度和NO浓度分布

分析了不同燃气管插入深度h下平展流火焰燃烧特性和NO生成特性。结果表明:减少h可以使燃烧区域扩大

从而降低火焰局部高温区温度

减少火焰面中NO浓度。

Abstract

High flame temperature in flat flame combustion will cause large amount of NO generation.Thus

the flame temperature and NO concentration in flat combustion with different burner structures were detected by WRNK armored chromium-nickel thermocouple and KM9106gas analysis instrument.Moreover

the open and flat flow flame combustion characteristics and NO formation characteristics with different gas tube inserting depths h were analyzed.The results show that reducing the h can enlarge the combustion zone so as to decrease the flame temperature in local high temperature regions and reduce the NO concentration in flat flame.
