Mine and Reclamation

The coal ash, or non-combustible portion of the coal, is collected from the bottom of the boiler or exits the boiler in the flue gas stream to be captured using dust collection devices. These residue products include fly ash, bottom ash, boiler slag, and other clean-coal combustion materials. Fly ash has a powdery appearance and fine texture.

The Usage of Coal Combustion (fly) Ash as Mitigation

In the last few decades, the utilization of coal to generate electricity was rapidly increasing. Consequently, the production of coal combustion ash (CCA) as a by-product of coal utilization as primary energy sources was increased. The physical and geochemical characteristics of CCA were site-specific which determined by both inherent coal - source quality and combustion condition.
