Application of the two-dimensional laser Rayleigh technique to the investigation of a large-scale industrial combustor is reported for the first time to our knowledge. Two-dimensional laser Rayleigh scattering was used to perform quantitative measurements of the temperature fields in different downstream positions of a 150-kW industrial, premixed, turbulent low-emission swirl combustor. Because of the possible interferences of the Rayleigh signal with Mie scattering and laser reflections of the burner components, some minor modifications of the design of the combustor and its gas supply were necessary. This was done without changing the basic characteristics of the burner. The quantitative and instantaneous character of the collected data allows calculation of ensemble-averaged temperature distributions and analysis of the flame structure in the turbulent combustion field. The measured temperature distribution confirms that the flame is stabilized by a central recirculation zone.
据我们所知，二维激光瑞利技术首次应用于大型工业燃烧器的研究。二维激光瑞利散射用于对一个150千瓦的工业预混湍流低排放旋流燃烧器不同下游位置的温度场进行定量测量。由于瑞利信号可能会受到米氏散射和燃烧器部件激光反射的干扰，因此需要对燃烧器及其气体供应的设计进行一些小的修改。这样做并未改变燃烧器的基本特性。所采集数据的定量和瞬时特性使得能够计算总体平均温度分布，并分析湍流燃烧场中的火焰结构。测量得到的温度分布证实火焰由一个中心回流区稳定。
