This report covers the first twelve months of the project {open_quotes}Radiative Properties of Char, Fly-Ash, and Soot Particles in Coal Flames{close_quotes}, that is from September 15, 1992 to September 15, 1993. The objectives of this project can be summarized as follows: (1) obtain the effective radiative properties of pulverized coal/char and soot particles, and (2) determine the concentration distribution of char, fly-ash, and soot particles in coal laden flames as a function of different flame conditions. Research accomplishments in the following areas are described: effective properties of coal and char particles; multilayer sphere model; soot formation model; and soot radiative properties. The experiments are described and plans for future work are outlined.
