No.1-11 Study of factor affecting sulfate compounds of coal ash

Abstract

It is known that decrease in flowability and hardening of coal ash is due to moisture absorption and compression during transportation and storage. This can lead to blockage accidents of coal ash in the hopper and pipe and similar situations. In this paper, the sulfate amount and compounds that affect the moisture absorption of coal ash were investigated. As a result, it was found that sulfuric acid mist and compounds on the coal ash combine to form sulfate compounds. The adsorption capacity of the sulfuric acid mist is affected by the coal ash characteristics.
