73.石炭灰の粒径分布測定

抄録

Laser diffraction and scattering method is the popular method in particle size analysis. However this method is good for operation, the refractive (or relative-refractive) index is necessary to analyze the size distribution. In this study, the optimum relative-refractive index in measuring coal ash was determined. If particles less than 1μm are included in coal ash, there is a possibility that the size distribution of the particles can't be evaluated accurately.
