Abstract
The objective of this research program is to determine (a) the radiative properties of coal particles, and (b) concentration distribution of char, fly-ash and soot particles in coal laden gaseous flames. During the first six months, we have concentrated on determining the effective optical and radiative properties of coal particles. This information is necessary to separate coal concentration from that of other particles. For this (1) in situ scattering and (2) ex situ spectrometer experiments were completed, and (3) a computer program was developed to model non-homogeneous, irregular shaped coal/char particles as radially inhomogeneous effective spheres. In addition to these studies, the new experimental system has been designed and built to perform the required experiments.
