Abstract
Several combustion characteristics which play a role in the radiation of flames are reviewed. The limits of inflammability of various combustible mixtures used in analytical flame spectroscopy, together with their ignition temperature, burning and detonation velocity and detonation pressure are examined briefly. The structure of premixed and diffusion flames at various pressures is described in some details and the radiation of several elements excited in the various zones of premixed flames is examined. A procedure for eliminating the background radiations from the blue cone and outer cone of various flames is suggested. The flame temperature and its distribution is analyzed in relation to flame structure, and the meaning of this combustion characteristic in relation to the radiation phenomenon is discussed. Brief considerations of some reactions and ionization in flames follow, the article being concluded with a discussion of the size of atomized droplets and its influence in the calciumphosphorus interference.
