| 摘 要： | 氢是一种非常有前景的清洁可再生能源载体.掺氢燃料预混稀燃是当前开发清洁高效的低排放燃气轮机最重要的能源转化方式之一。本文基于预混CH4/H2/air本生灯火焰,对氢气掺混影响下的湍流火焰详细火焰结构进行了测量和表征。实验采用CH2O和OH基平面激光诱导荧光(PLIF,Planar Laser Induced Fluorescence)同步测量技术,获得了火焰预热区、反应区以及已燃区的详细火焰结构信息。本文对反应区和预热区火焰厚度进行了提取和统计。研究表明,氢气对火焰反应区、预热区均有明显作用。结果表明,掺氢小幅度增厚反应区厚度,但能够比较明显地降低预热区厚度。

| Abstract: | Hydorgen is a promising clean renewable energy carrier.The premixed combustion of lean hydrogen enriched fuels is one of the vital methods to develop low-emission gas turbine with high performance.The present study was focused on the influence of hydrogen addition on the detailed flame structure of turbulent premixed Bunsen flames using CH4/H2/air mixture.The preheat zone,reaction zone and burned zone were experimentally measured with simultaneous CH2O/OH planar laser induced fluorescence(PLIF)technique.The flame thickness of preheat and reaction zone was extracted and statistical analysis were performed.The results show evident impact from hydrogen addition on the flame structure.Especially,the hydrogen broadens the reaction zone slightly but largely decreases the preheat zone thickness. |
