INFRARED SPECTROSCOPY DIAGNOSIS FOR FLAME TEMPERATURE AND SPECIES CONCENTRATION
红外光谱技术诊断火焰温度和组分浓度的研究

Based on the theory of exponential wide band model of radiation absorption of gas molecules, the principle formulas of infrared spectroscopy diagnosis for flame temperature and composition concentration were deduced and a kind of practical calculating method was given. An infrared spectroscopy diagnosis system was established, and the experimental research was carried out with the system. The results show that the accuracy is relatively high, Thus, the aim to measure the flame temperature and composition concentration synchronously has been achieved.
