Analysis of infrared temperature measurement for flue gas shielding metal surface using Source Multi-Flux method
2016
The infrared temperature measurement technique has been applied in various
fields with the development of Charge Coupled Device (CCD). In the problem of
metal surface temperature measurement, if the surface is covered by
participating media, the traditional infrared temperature measurement
technique will lead to intolerable measurement errors. In this work, the
infrared temperature measurement problem was solved by the Source Multi-Flux
method. On this base, the impact of the flue gas thickness and surface
temperature on the apparent temperature measured by the CCD was analyzed.
Furthermore, the corresponding experimental system was set up. And the
experimental results were found to have a good agreement with the simulated
results. Finally, the idea of modification for the infrared temperature
measurement by inverse method was proposed.
