The Agency has defined economizer ash as bottom ash when "it is collected with the bottom ash" (40 CFR 423.11f) and as fly ash when "it is collected with fly ash" (40 CFR 423.11e).

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.
