So far, we have established the measuring method for pulverized particle coal distribution by an image analysis system with an optical microscope. In this method however, we need to assume a particle height by correlation with an equivalent particle diameter because only two-dimensional image information is available. Moreover, we use a constant particle shape coefficient as a sphere approximation to get an equivalent particle volume.
In order to decrease data processing time and secure confidence in measurement, we introduced a direct and consecutive particle height measuring technique using laser diodes. In this paper, we propose a new image analysis system with higher precision by incorporating a new particle shape coefficient into this technique. The particle diameter obtained by our method was compared with that acquired by our three-dimensional particle diameter measuring method. As a result, it was confirmed that our image analysis system can be more practically used.
