Where the incinerator is in constant 24-hour operation or is responsible for the combustion of high levels of waste over long periods, we have developed a number of automated de-ashing processes designed to reduce the necessity for manual labour to a minimum level.
Primarily employed within a stepped hearth configuration where the waste material is progressively propelled by a hydraulic ram through the different phases of combustion until it reaches the hot ash stage.
At this point a refractory lined hydraulically operated ash ram loader will force the combusted ash remains from the primary chamber into an ash vestibule that is sealed by a gravity closed ash release door.
Periodically, as the ash level accumulates, air is introduced into the ash vestibule to cool the ash and complete the combustion cycle before the ash door automatically opens to release the ash, allowing it to drop into a wheeled ash container ready for disposal.
Wet Bath Ash Conveyor
Following the main combustion process within the incinerator ash will periodically be discharged via a hydraulically operated ash release gate. This allows the hot ash to drop into a water bath that firstly quenches the temperature and then stabilises the ash to prevent any wind dispersion.
A continuous loop flighted chain conveyor operates to sweep up the ash before transporting it into a separate road transportable ash skip.
The operation of the conveyor is automatically controlled to coincide with the opening of the ash release door.
