convective drying of pond fly ash

Jan 01, 2017 In a recent study of a large ash pond in China (Duvallet, Robl, Henke, Zhou, & Harris, 2016), it was found that even a small amount of codisposed gypsum (Ca 2 SO 4 2H 2 O) resulted in higher levels of sulfate in the ponded ash, as well as particle sizes that were much coarser compared to dry fly ash collected from the plant. 14.3.2.
