The Clyde Bergemann Delta Ducon Vacuum/Pressure Ash Transfer System is the solution selected by many plants to convey their fly ash dry. As power plants are demanded to reduce their water usage and minimize or eliminate their ash storage ponds, a growing need is presented to convert existing water powered fly ash systems into dry conveying and storage systems.
 
 
 
Clyde Bergemann Delta Ducon has the experience and technology required to convert existing OEM wet fly ash systems to completely dry collection systems. This will totally eliminate the need and use of water and ash ponds.
 
As part of the dry ash conversion, Clyde Bergemann Delta Ducon has also upgraded the entire fly ash control system providing the latest technology in ash handling logic. In addition, plants have also benefited from the sale of the dry fly ash into cement and building industry.
 
 
 
 

In most plants, fly ash is vacuumed from beneath collection hoppers. The motive air for these existing vacuum systems is provided by a water powered venturi. The Vacuum/Pressure Ash Transfer System eliminates the need of the water powered venturi by providing the motive air and vacuum via a mechanical vacuum blower.
 

 
 
 

With the Vacuum/Pressure Ash Transfer System, ash is diverted into a dry collector/filter where it is separated from the vacuum conveying air stream.
 
As with many plant retrofits, finding a nearby location for a new dry ash storage silo can be an issue.
 
The Vacuum/Pressure Ash Transfer System transfers the ash collected by the vacuum system into a pressure transport line that will transport the ash to the storage point no matter how far away the ash silo is placed.
