The Spectral Growth of Expanding Flames: The Infrared Radiance of Methane-Air Ignitions and Coal-Dust-Air.

PB223785

Publication Date	1973
Personal Author	Hertzberg, M.; Litton, C. D.; Donaldson, W. F.; Kuchta, J. M.; Furno, A. L.
Page Count	43
Abstract	Results are reported of a comprehensive study of the absolute spectral radiance of the infrared emissions from methane-air explosions. The spectral growth of these expanding flames are recorded with a time resolution of one msec in the spectral range of 1.7 to 5.0 microns. Time-solved spectra were obtained for methane-air mixtures as a function of stoichiometry, nitrogen dilution and Halon dilution, in a 9-liter vessel under different venting conditions. Data are also presented for coal-dust-air explosions.
