This study is to evaluate the radiation properties of coal char and ash particles. Char in coal-firing and gasification processes exists as heterogeneous composite particle particles consisting of nano-order fine particle made of mainly soot and micron-order particle of carbon and ash component. The effect of carbon content in char particle on extinction efficiency of the particle cloud could be measured reasonably by a pretreatment of the original char classifying the particle size with a wet method. Extinction efficiency could be correlated by a simple function of carbon content using the properties of carbon-free ash and carbon without ash components treated by hydrofluoric acid.
