| 摘 要： | 为了解中低热值合成气在燃气轮机燃烧室中的燃烧特性,利用平面激光诱导荧光(PLIF)法,对模型燃烧室内CH4和具有不同C-H比的合成气旋流扩散火焰开展实验研究.实验结果表明,CH4与合成气火焰呈现出截然不同的火焰形状,瞬态OH-PLIF图像揭示了它们具有湍流火焰的共同特征,且火焰都稳定在喷嘴出口位置.相比之下,CH4燃烧...

| Abstract: | Planar laser induced fluorescence (PLIF) measurement was conducted on swirling non-premixed flame in a model combustor,firing CH4 and syngas with different C-H ratios,in order to study the combustion characteristics of mid-caloric syngas flame in a gas turbine combustion chamber.Although quite different flame shapes were found between CH4 and syngas flame,instantaneous OH-PLIF images demonstrated the common turbulent flame features.Results also show that both flames are stabilized at the exit of the fuel injector,but CH4 flame burns more steadily.Quantitative analysis of flame reaction core shows that flame stability deteriorates with the increase of C-H ratio. |
