Pressure Pneumatic Ash System
Schematic - Pressure Pneumatic Ash Collection/Ash Conveying System

Pressurized pneumatic ash handling systems are most often used for conveying ash over long distances. Such systems are also usefully applied when ash is to be delivered to multiple interim storage or load out stations.

An upstream mechanical blower creates a flow of conveying air. Ash is transferred from collection hoppers to the conveying pipeline on a programmed cycle with the use of rotarty airlock feeders or double dump gate airlock valves.

At the end of the ash conveying pipeline ash is received in a highly abrasion resistant silo mounted target box from which it falls by gravity into the storage silo.

Ash conveying air is normally exhausted to the atmosphere through a silo vent filter or it can be recycled to other dust collection equipment.
