Ash handling systems may employ different forms of pneumatic ash conveying or mechanical ash conveyors. A typical ash handling system may employ vacuum pneumatic ash collection with ash conveying from several ash pick up stations and resulting in delivery to an ash storage silo for interim holding prior to load out for disposal or reuse.
May 07, 2014· Requirement of Ash Handling System In Thermal Power Plant's coal is generally used as fuel and hence the ash is produced as the byproduct of Combustion. Ash generated in power plant is about 30- 40% of total coal consumption and hence the system is required to handle Ash for its proper utilization or disposal.
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.
