Abstract
The spectral radiance of several flames in the 2-15-µ wavelength region have been measured using a low-resolution infrared spectrometer. The spectral absorptivities have been determined, and this information combined with the radiance measurements has led to a determination of the flame temperature. The techniques of measurement and calibration are described including the important effects of the spectrometer slit width and atmospheric attenuation both on the calibration and the measurements.Keywords
