Dry Bottom Ash Handling System

With hundreds of installations worldwide since the 1980 s the mac is the world s leading dry bottom ash handling system for utility and industrial boilers of any size and burning any kind of solid fuel.

Dry bottom ash handling system.

Because of the complete elimination of water this system provides increased lifetime reduced cost and required time. The process uses a vacuum design to convey ash to the point of shipment for external use. This results in a lower cost because there is no need to dispose of or treat the water that is used in a wet process plus there are lower emissions and heat energy. These technologies offer environmentally sound solutions to address wet fgd scrubber wastewater and mitigate ash storage ponds.

Vacuum pneumatic conveying of dry bottom ash is the most popular system. These systems frequently continue to burn bottom ash using ambient air instead of water during the extraction and cooling phases. The vax system is the most cost effective and rugged dry bottom ash handling system available. As part of our complete environmental technologies line we continue to provide a variety of ash and material handling solutions from completely dry bottom ash handling to fly ash and petroleum coke processing.

The mac magaldi ash cooler is a unique system for dry extraction air cooling and mechanical handling of bottom ash from pulverized coal fired boilers. The dry fly ash system consists of a two stage esp and duct hopper ash removal conveying system.
