Abstract
Pentannual surveys of the production of coal combustion byproducts in Kentucky utility power plants, along with other studies in the intervening years has resulted in a large amount of data relating coal chemistry, fly ash (FA) chemistry, and, to a lesser degree, bottom ash chemistry. Therefore, this important collection of data enables to perform studies on a wide variety of fly ash types. The chemical classification, based on major oxides (acid, alkaline, and Fe2O3), of coal high-temperature ash (HTA) and FA from Kentucky Power Plants shows that the majority of the coal HTAs are Sialic, Sialic-Ferrisialic, and Ferrisialic. The FA classification not only depends of the coal HTA chemistry but also the ash-collection system and the sampling position, with the implications of flue gas temperature and ash particle size, within the system.
