摘要: 为了研究辐射参与性烟气对红外测温法金属壁面温度测量的影响,首先根据实验中红外探测器测量得到的表面温度分布的特点,建立了一维表面红外测温模型;然后根据红外热成像测温原理及辐射传输理论,利用源项多流法分析模型计算了烟气覆盖表面在不同烟气厚度和不同表面温度下红外探测器获得的温度;最后利用马弗炉模拟不同温度的表面,振动筛模拟不同浓度和厚度的烟气环境,在实验室条件下设计搭建了模拟烟气覆盖表面的红外测温实验系统,实验验证了源项多流法分析模型,实验测量得到的温度与分析模型预测的温度吻合较好,并提出了利用反演方法修正红外测温的设想。

Abstract: Radiative participant flue gas has important influence on the infrared surface temperature measurement of flue gas covering surface. According to the characteristic of the sample temperature distribution measured by an infrared CCD camera, a simplified one-dimensional model of infrared surface temperature measurement is established. Based on the simplified model, the detected infrared temperatures at different thickness of flue gas and surface temperature of sample are analyzed using source multi-flux method. Finally, a muffle furnace is used to heat the measured surface, and a vibrating screen is used to simulate flue gas covering environment. An infrared temperature measurement system is built for flue gas covering surface. The analytical model of source multi-flux is verified by the experiments, and the measured temperature by the experimental has a good agreement with the predicted temperature by the analytical model. The idea of modification for the infrared temperature measurement by inverse method is proposed.

Key words: infrared temperature measurement, source multi-flux method, radiance transfer, participating media, temperature correction
