摘要

摘要:
采用了一种阵列安装的微管喷嘴模型燃烧器，通过交叉射流实现燃料与氧化剂的高效混合，在水蒸气环境下开展了氢氧燃烧特性研究。通过数值模拟验证了微管在水蒸气环境下的稳火性能。在常压条件开展了水蒸气环境下氢氧燃烧试验，获取了燃烧器的火焰图像、点熄火边界、燃烧效率以及压力脉动特性。结果发现，提高水蒸气温度可以明显拓宽燃烧器的点熄火边界，各工况下氢气的燃烧效率都高于99.9%，各工况下燃烧器的压力脉动都处于较低水平。初步验证了该模型燃烧器在水蒸气环境下能保证氢氧高效燃烧，且不易发生燃烧振荡。

Abstract:
An arrayed microtube nozzle burner was employed in achieving efficient fuel and oxidizer mixing through cross-jet flows. Research on the combustion characteristics of hydrogen and oxygen in a steam environment was conducted. Through numerical simulation, the flame stability of the micro tube in steam environment was verified. The combustion efficiency of arrayed model burner with different microtube spacings was also contrasted. Experiments on the combustion of pure hydrogen and oxygen in a steam environment were carried out under atmospheric conditions. Flame images, ignition and extinction boundaries, combustion efficiency, and combustion oscillation characteristics of the burner were obtained. The results indicated that increasing steam temperature can significantly widen the flame ignition and extinction boundaries of the burner. The combustion efficiency of hydrogen was kept above 99.9% under various conditions, and the pressure fluctuations of the burner were at relatively low levels. This initially validated that the proposed burner can ensure efficient combustion of hydrogen and oxygen in a steam environment, with minimal combustion oscillations.
