It is known that decrease in flowability and hardening of coal ash is caused by moisture absorption and compression during transportation and storage, and could lead to blockage accidents of coal ash in hopper and pipe and so forth. In this paper, we investigated the sulfate compounds amount that affects the moisture absorption of coal ash. As the result, the content of sulfate compounds in coal ash depends on compounds in coal and sampling points. Also, most of sulfate compounds were produced by the reaction of sulfuric acid mist and compounds in coal ash.
