研究了基于可调谐二极管激光吸收光谱(TDLAS)技术的火焰CO2浓度检测方法,确定了TDLAS二次谐波检测在高温环境下的浓度反演方法,并在实验室通过静态吸收池进行了验证,为TDLAS遥测系统应用于工业燃烧测量打下了基础。
The measurement method of CO2 concentration was developed in high-temperature environment based on tunable diode laser absorption spectroscopy. The concentration quantification with second-harmonic detection was adopted and verified in laboratory with static-cell. These researches are useful foundations for industry combustion applications.
