中文摘要：

基于Mckenna标准层流火焰燃烧器,利用瑞利散射和热电偶方法对典型低热值合成气预混层流火焰的温度进行精确测量,并将两种测量方法所得的结果与CHEMKIN化学动力学数值计算结果进行对比。三种试验结果显示,利用瑞利散射方法所测的温度介于CHEMKIN数值计算与热电偶结果之间。原因在于CHEMKIN4.1数值计算是基于绝热状态的假设,因此计算的温度高于实际温度;而瑞利散射所测温度比热电偶高150 K。可见,相比传统热电偶测温,瑞利散射测温在气体燃料的火焰温度场定量测量更加准确。

英文摘要：

The premixed laminar flame temperature measurement of the low heat value syngas was conducted in a Mckenna burner precisely. Both Rayleigh Scattering（ RS） and thermal couple were attentively employed to make the temperature measurement. Furthermore,the comparisons of two measurements with CHEMIN calculation result were carried out. The temperature detected by RS was over 150 K than that of thermal couple,but lower than CHEMKIN result. RS seemed satisfactory and validated as a good approach for quantitative measuring the premixed laminar flame temperature.
