Abstract

A pyrometric method was developed earlier for the simultaneous in situ measurement of the temperature and the size of combusting fuel particles in entrained flow reactors. The temperature measurement is based on two-color pyrometry and the particle sizing on the proportionality of the measured radiative flux and the cross-sectional area of a particle at a known temperature. This particle-sizing method needs a discrimination procedure to confirm that the detected particle is valid for particle sizing. We report on a novel method for particle discrimination based on coaxial reference optics. The new method has several advantages compared with the method presented earlier, including the measurement in turbulent flow fields.
