Spectral Distribution of Different Regions in Illuminating Flare Flames II.

Abstract

Stoichiometric and fuel rich illuminating flare compositions containing magnesium, sodium nitrate and 4.5% epoxy binder were burned at ambient pressures of 630/150/30 torr in air. Grating spectra with a reciprocal dispersion of about 11A/mm were obtained with an astigmatic spectrograph by focussing an image of the flame on the slit. The resultant spectrogram was analyzed to obtain the relative spectral radiance of the flame as a function of height along the central axis of the flare candle. It was found that changes do occur in the spectral distribution with increasing height above the candle.
