One of the major problems in pulverized coal combustion process is ash deposit phenomena such as slagging and fouling. The behaviors of Included Minerals (IM) and Excluded Minerals (EM) are an important factor to predict and control such ash deposit phenomena. Then, we sampled pulverized coal particles in different carbon conversion and coal types using Drop Tube Furnace (DTF) and analyzed ash particles by Computer Controlled Scanning Electric Microscope (CCSEM) in previous study3). In this study, we made the models of single pulverized coal particle in combustion process using data gotten by CCSEM analysis and evaluated IM/EM particle properties such as particle number, particle diameter and composition in different carbon conversion and coal types through the simulation.
