Bottom ash is most commonly conveyed in a hydraulic system in which the ash is entrained in a high flow, circulating water system and delivered to either an ash pond or to a remote dewatering device. Alternatively, mechanical drag systems have been used to convey bottom ash to the dewatering storage bin because they use less water and usually have a lower initial cost.

Ash Handling Plant

An ash handling system consists of some subsystems such as bottom ash (BA), fly ash (ESP/air heater), ash water, and ash disposal systems. The ash handling system may be dry (dry pneumatic conveying is more popular now on account of retention of original characteristics of fly ash and its utilization), semiautomatic wet, and a wet system.
