Mechanical Handling of Dry Fly & Bottom Ashes in PCF Power Plants
MAS® - Magaldi Ash System

The MAS® (Magaldi Ash System) is a patented integrated dry mechanical system for handling all ash from solid fuel fired boilers, allowing a dependable and economical management for both fly and bottom ash.

The MAS® (Magaldi Ash System) is a patented integrated dry mechanical system for handling all ash from solid fuel fired boilers, allowing a dependable and economical management for both fly and bottom ash.

The MAS® comprises 3 subsystems, as follows:

  • the mechanical conveying of fly ash through the Magaldi Ecobelt® FA;
  • the MAC® (Magaldi Ash Cooler) system, for dry extraction, cooling and handling of bottom ash;
  • the MAR® (Magaldi Ash Recycling) system, for dry bottom ash and economizer ash recycling in the combustion chamber, to convert them into fly ash.

The MAS® properly addresses the demand of solid fuel fired power plants for sustainable practices in ash handling. Dry coal combustion products (CCPs) can directly contribute to achieve environmentally sound methods of disposal.
Using CCPs, in cement or concrete production rather than disposing of them, conserves natural resources and reduces greenhouse gas emissions. The safe and beneficial use of dry ash should be viewed as a preferred alternative to ash ponds, avoiding the need for additional landfill space through sound technical and environmental management practices.
One single integrated mechanical ash conveying and storage system is simpler, more efficient, and increases the market value of the ash.
The result is the production of only fly ash, as the coal combustion by-product.
