Abstract

A data reduction scheme for multiple-wavelength, line-of-sight, optical pyrometry applied to pulverized-coal flames that accounts for the presence of soot and its effect on computed temperatures is presented. Results of the application of the technique to laboratory scale flames are reported. Soot temperatures are calculated to be between gas and particle temperatures, with the gas temperature exceeding the particle temperature. From about 1 to about 10 percent of the original coal by mass is computed to be present as soot in the flames with soot concentration increasing with increasing coal concentration.
