Stock Redler De-Asher Case Study

A STOCK REDLER Ash Handling system is located below a Foster Wheeler pulverised coal fired boiler that produces some 300 tonnes of steam per hour.

Ash drops from the combustion chamber via a water cooled drop chute into the submerged ash conveyor filled with brackish or occasionally sea water.

Ash is discharged to a skip hoist via a chute that facilitates the trapping and removal of large clinkers. The skip hoist elevates ash to the top of a storage silo with the operation being automatically controlled by means of a load cell system. Discharge to road is through a clam-shell type discharge gate.
