近年来各类间歇性新能源发电大力发展，为了满足不稳定能源的消纳问题，作为过度中间能源的氢能被广泛使用。然而氢气在燃烧过程中稳定性较差，NOx排放高，理论上在微混燃烧器中有着较好的燃烧特性，但较为缺乏实验数据支撑。本文针对微混燃烧器中10kW甲烷掺氢混合气的燃烧特性进行研究。结果显示，随着α_(H_2 )增加，火焰稳定性提高，当 α_(H_2 )≥40%时火焰稳定性较好。α_(H_2 )增加时，火焰尺寸减小，颜色由明亮的蓝色向淡蓝色转变，在纯氢状态下激发态水蒸气的红色尾焰占据主导。NOx排放随α_(H_2 )增加而增加，但转化为纯氢燃烧时排放量降低。φ增大时，火焰颜色变暗、规模增大，燃烧室各部分温度上升，NOx排放量在φ＞0.4和φ＜0.4区间内呈相反的变化。

In recent years, various types of intermittent new energy generation have been vigorously developed, and in order to meet the problem of unstable energy consumption, hydrogen energy as an excessive intermediate energy is widely used. However, hydrogen has poor stability in the combustion process and high NOx emission, and theoretically has better combustion characteristics in a micro-mixing combustor, but there is a lack of experimental data to support it. In this paper, the combustion characteristics of a 10kW methane doped hydrogen mixture in a micro-mix combustor are investigated. The results show that the flame stability increases with the increase of α_(H_2 ), and the flame stability is better when α_(H_2 ) ≥ 40%. When α_(H_2 ) increases, the flame size decreases, and the color changes from bright blue to light blue, and the red tail flame of the excited state of the water vapor in the pure hydrogen state is dominant. The emission decreases. φ increases, the flame color darkens, the scale increases, the temperature of each part of the combustion chamber rises, and the NOx emission changes in opposite directions in the φ > 0.4 and φ < 0.4 intervals.
