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.
mixer / conditioner / unloader effectively transforms dry fly ash into uniformly wetted ash resulting in a completely controlled, efficient and dust-free operation with capacities ranging from 1 to 400 tons per hour. Larger units are available upon request.
Coal handling plant consists of track hopper,feeders, conveyor system, roller screen, crusher, stacker reclaimer, compressor,dfds system,ttr,pumps etc.

A Mechanical Ash Handling System is often the best choice for fluidized bed ash where headroom is restricted under the boiler. The Mechanical Ash Handling System handles the ash by Bottom Ash Handling System, Fly Ash Handling System, Ash disposal system up to the Ash disposal area and water recovery system from ash pond and Bottom ash overflow.
The controlling system used is typically a PLC (programmable logic controller) with an HMI (human-machine interface) for display connected to a central control system. Other than stacking, the stacker does three basic movements: luffing, travelling and slewing. Luffing: This is vertical movement (that is, up & down)by hydraulic cylinders .
This system is suitable, where coal is to be transferred over shorter distance and space limitations exist. The initial cost of the system is low. It suffers from the drawbacks that the power consumption is high and there is considerablewearofscrew. Rotation of screw varies between 75-125 R.P.M.

Jun 23, 2015· Systems that use impounded hoppers or submerged scrapper conveyors have traditionally handled ash using water as a primary medium. Now, however, a growing emphasis on environmentally-friendly production has caused many power plants to reconsider elements of their production process that aren't green – and that includes ash handling.
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.
