基于双光梳吸收光谱的燃烧气体温度测量方法
Combustion Gas Temperature Measurement Based on Dual-Comb Absorption Spectroscopy
摘要
Abstract
Flame temperature measurement is a much talked about test technology issue,and laser spectroscopy diagnostic methods are being widely used from contact to non-contact measurements.Among them,dual-comb absorption spectroscopy has been developed in recent years because of its wide spectral range,fast measurement speed,high signal-to-noise ratio,and no need for mechanical structure.Most of the current research is in the use of this technique to measure the temperature of gases such as methane,failing to measure the flame directly.In this paper,by evaluating the stability of the dual frequency comb spectroscopy so that the overall spectral stability is within 2％,and then with the combustion absorption device,the signal absorbed by the flame is collected in a continuous mode,and combined with the double line absorption method,the average temperature of the absorption path was initially calculated to obtain the temperature distribution.The temperature trend is basically the same when it is compared with the thermocouple,which provides a reference for the measurement of flame temperature.关键词
