摘　　要：为了获得掺氢对常规天然气燃烧和排放性能的影响规律,基于燃气轮机模型燃烧室开展了常温常压条件下不同比例富氢燃气的燃烧及排放特性实验研究。采用粒子图像测速和激光诱导荧光技术获得了旋流火焰流场与火焰宏观形态特征,同时对其贫燃熄火边界、出口排放特性进行定量测量和分析。结果表明,掺氢燃烧会显著改变甲烷旋流火焰的宏观形态、贫燃熄火边界和出口排放特性。研究发现:掺氢有利于提高燃烧强度和稳定工作范围,在当量比为0.5的较贫燃条件下可以较好地控制CO和NO排放,其浓度均不超过10^(-5)。同时,采用层流火焰传播速度等基础燃烧特性参数可以较好地捕捉燃料特性变化引起的旋流火焰尺寸、熄火边界的变化规律。To obtain the impacts of hydrogen addition on the combustion and emission of natural gas,exper⁃imental studies on the combustion and emission characteristics of hydrogen-enriched fuels with different hydro⁃gen blending ratios were carried out in a gas turbine model combustor at normal pressure and temperature.Parti⁃cle image velocimetry(PIV)and laser-induced fluorescence(PLIF)measurements were utilized to obtain the flow field and macrostructure of the swirl flames,while the lean blowout limits and exhaust emission characteris⁃tics were quantitatively measured and analyzed.The results show that hydrogen enrichment can significantly change the flame macrostructure,lean blowout limits,and emission characteristics of methane.It was found that hydrogen addition is conducive to enhancing the combustion intensity and extending the stability envelope,while the CO and NO emissions can be well controlled,not exceeding 10^(-5),under leaner conditions with an equiva⁃lence ratio of 0.5.Meanwhile,the fundamental combustion parameters,such as laminar burning velocity,can be used to characterize the impact of different fuel features on flame size and lean blowout limits of the swirl flames.
