Loibl's LASHDRYPRON® ensures the discharge of bottom ash and cools slag by means of cooling air flowing into the conveyor through control dampers and openings with non-return valves. In the event of a malfunction of the slag conveyor, the hydraulically driven flaps in the slag chute are closed. This way, the conveyor system is separated from the furnace. If unburned residues ignite in the deslagger, the dry extinguishing device is triggered by temperature measurements. Boiler ash from a feed tank is preferably used for extinguishing. As a final fire-fighting measure, the extinguishing nozzles with which the deslagger is equipped are activated.

An enclosed particle separator at the outlet of the dry deslagger ensures that coarse fragments fall into a container. The remaining slag is picked up by an apron conveyor and cooled down further. This is followed by a belt conveyor that transports combustion residues to the slag hall, where FE metal separation takes place using an overband magnet. Furthermore, the slag is discharged onto a belt conveyor leading to the slag processing plant. In addition, the slag can be diverted to three separate containers via reversible belt conveyors.

The boiler ash is discharged with discharge screws. It enters a trough chain conveyor via a crushing rotary valve. Trough chain conveyors combine the boiler ash from the various boiler passes. Fly ash discharged from the fuel bed is separated in the boiler area and transported to the boiler ash silo by a mechanical boiler ash conveyor. There it can be discharged from the silo via a crushing rotary valve. For unloading the silo, a loading bellows was installed, which ensures dust-free unloading by means of a dust extraction system.
