Ash Handling is the method of collecting, Storage and conveying ash

from various ash residue left over from the combustion of coal.

The types of ash include bottom ash and fly ash and resulting from the

combustion of coal. Ash handling systems may employ pneumatic ash

conveying or mechanical ash conveyors.
