| 摘 要： | 燃烧场温度的测量对研究燃烧机理、提高燃烧效率、降低污染物排放等至关重要。利用水在1397.75 nm和1397.87 nm处两条邻近的吸收线,采用波长扫描直接吸收法实现了单台二极管激光器对标定燃烧炉甲烷/空气预混火焰温度的测量。并利用基于Labview语言的数据采集卡对信号进行采集和实时处理,从而能够实时在线地获得测量结果,在温度1750 K时标准测量不确定度为2.3%。分析了火焰边界层对测量结果的影响,结果表明燃烧场非均匀性对路径积分测量结果影响较大,且其测量结果不是路径积分算术平均值。

| Abstract: | Measurement of combustion temperature is critical to understand combustion processes,improve combustion efficiency and reduce the production of pollutants.A single diode laser sensor system is established to obtain on-line measurement results of combustion temperature.The measurements are performed in a flat burner based on scanned-wavelength direct absorption spectroscopy by using two adjacent water lines 1397.75 nm and 1397.87 nm.The real-time results are acquired by using a DAQ card with Labview data pro... |
