摘要

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燃烧更加稳定,通过对火焰核心反应区域的定量分析还发现,C-H比越高,合成气火焰的稳定性越差.

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.
