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.

A thermal spraying technique was adopted to change the surface properties of heat exchanger tubes in pulverized coal fired boilers in order to reduce ash deposition. Initially, four types of coal ash with different melting points were tested as samples for ash deposition experiments. As a result, ash particles with higher fouling factor selectively adhered on the tube surface. Even for the ash particles with lower melting point, Ni alloy as a thermal spraying material played an effective role in reducing deposition. Ni alloy can reduce the ash deposition by limiting formation of molten slag at high temperature. In addition, long-term ash adhesion experiments were also carried out using a precise tension tester at high temperature. The effectiveness of the Ni alloy was also proved after long term contact between an ash pellet and a rod thermally sprayed Ni alloy at high temperature. This is because the Ni alloy can control the diffusion of Fe compounds from the tube rod to the ash deposition layer.
