From a standpoint of utilization of low rank coals, flexibility to a variety of coal types as fuel is increasingly needed in pulverized coal fired boilers. If coal which physical properties are far from those of the design coal is used in the boiler, ash deposit troubles called fouling and slagging become much more severe. Therefore mineral particle behaviors in coal combustion are studied for different types of coal samples in this study. Coals having low, middle and high melting points of ash are burned in a drop tube furnace to sample char particle in different conversion ratios. Then included and excluded minerals are analyzed in char particles via CCSEM.
