摘　　要：将低浓度瓦斯作为助燃空气,天然气作为主燃料,在微型燃气轮机内进行燃烧实验。通过燃气轮机实验,分析CH4在燃气轮机内燃烧后排放的烟气成分,在实验所得数据基础上进行Fluent数值模拟,得到燃气轮机燃烧室的流场、温度场分布,以及排放烟气中NO含量分布。The combustion experiment taking low concentration gas as oxidizing air and natural gas as main fuel is carried out in a micro gas turbine to analyze the constituent of the flue gas after CH4 burning in the combustor. Based on the experimental data, the Fluent numerical simulation is conducted to get the distribution of flow field, temperature and the NO in flue gas. The simulated results are basically consistent with the experimental data.
