摘要

面向高温工业低碳转型，氨作为零碳燃料具有广阔应用前景，但低反应活性制约了其应用。富氧燃烧通过提升氧化剂（O

）含量，可有效提

升燃烧稳定性。然而，目前针对高温工业工况下氨氢预混旋流火焰的研究仍显不足。基于kW级工业旋流燃烧器实验平台，结合雷诺平均模拟与化学反应器网络模型，研究了空气助燃（氧气体积分数为21%）与富氧条件（氧气体积分数为25%）对低裂解率氨氢预混旋流火焰稳燃及排放特性的影响。结果表明，富氧燃烧显著拓宽了稳燃极限，随着氧气体积分数升高，火焰形态由“V”形转变为直筒形；烟气中未燃NH

与NO之间呈竞争-抑制关系，协同低排放窗口由过量空气系数（

）≈ 1.2（氧气体积分数为21%）前移至

≈ 1.1（氧气体积分数为25%）。数值模拟结果表明，富氧条件相较空气助燃使火焰OH峰值提升约24%，通过NH

+ OH ⇌ NH

+ H

O（R278）等反应加速氨氧化，同时抑制NH

中间体向N

转化，促使活性氮更多流向NO生成方向。相关研究结果阐明了富氧强化氨燃烧的机制及其排放权衡关系，可为高温工业氨燃料清洁高效应用提供理论与实验依据。

Abstract

To address the low-carbon transition in high-temperature industries

ammonia has broad application prospects as a zero-carbon fuel

yet its low reactivity restricts its application. Oxygen-enriched combustion

which increases the oxidant (O

) content in the oxidizer

can effectively enhance combustion stability. However

current studies on ammonia-hydrogen premixed swirling flames under high-temperature industrial conditions remain insufficient. Based on a kW-scale industrial swirling combustor experimental platform

combined with Reynolds-averaged simulation and a chemical reactor network model

the effects of air-assisted combustion (oxygen volume fraction of 21%) and oxygen-enriched condition (oxygen volume fraction of 25%) on the flame stabilization and emission characteristics of low-cracking-ratio ammonia-hydrogen premixed swirling flames were investigated. The results show that oxygen-enriched combustion significantly broadens the flame stability limits. As the oxygen content increases

the flame shape changes from a “V” shape to a cylindrical shape. A competitive-inhibition relationship between unburned NH

and NO in the flue gas is observed

and the synergistic low-emission window shifts forward from an excess air ratio (

) of approximately 1.2 (oxygen volume fraction of 21%) to

≈ 1.1 (oxygen volume fraction of 25%). Numerical simulation results indicate

that

compared with air-assisted combustion

oxygen-enriched condition increases the peak OH concentration of the flame by approximately 24%

accelerating ammonia oxidation through reactions such as NH

+ OH ⇌ NH

+ H

O (R278)

while suppressing the conversion of NH

intermediates to N

thereby promoting more reactive nitrogen toward NO formation. The relevant results clarify the mechanism of oxygen-enriched enhancement of ammonia combustion and its emission trade-off relationship

providing theoretical and experimental support for the clean and efficient application of ammonia fuel in high-temperature industries.
