Abstract
A multiple-wavelength, infrared pyrometer suitable for making line-of-sight particle and gas temperature measurements in pulverized-coal flames is described. The pyrometer uses lead selenide detectors covered with narrow-band filters to measure emitted and transmitted radiation. Scattering effects may be and are here incorporated into data reduction schemes for calculating temperatures. Measurements were made on one-dimensional, coal-dust/oxygen/argon flames stabilized on a flat-flame burner. Profiles of particle and gas temperatures and optical depths as a function of distance from the burner are presented. In general, particle and gas temperatures do not differ much close to the burner, but farther downstream the gas temperature exceeds the particle temperature.Keywords
