Characteristics and Utilization of Unburned Carbon in Fly Ash

Pulverised coal fired power plants annually produce a huge amount of fly ash, which is a very important resource to this country. Lowering its unburned carbon content of fly ash can not only promote the high value utilisation of fly ash, and also recover the valuable carbon. In the present paper, the studies on the characteristics of unburned carbon and the separation technologies were reviewed. The effects of the characteristics on the carbon separation and utilizations were analyzed and stressed. Consequently, the carbon utilizations and their prospects were discussed.
