BROOKFIELD, WI (NOVEMBER, 2000)…
HEIL ENGINEERED SYSTEMS recently completed a new boiler bottom ash and fly ash handling system for Montenay Power Corp. at the Miami-Dade County Resource Recovery Facility. The new system replaced a troublesome ash handling system that was prone to blockages, spillage, and unscheduled downtime. All four boilers burn 100% RDF, which is produced by one of two fuel preparation systems, provided by Heil in 1990 and 1997.
The new system included the following:
Submerged drag conveyors to handle the boiler siftings on all four boilers.
Screw conveyors to handle the boiler fly ash on all four boilers.
Vibratory conveyors on each boiler to handle the combined bottom ash, siftings, and fly ash.
Common belt conveyors to transport the collected ash to a loadout building.
A new ash processing building which contained a magnetic separator and eddy current separator to automatically remove residual ferrous and non-ferrous from the ash.
A ferrous and non-ferrous loadout bunker with transport conveyors.
System electrical controls including motor starters, touch screen interface, and tie in to boiler DCS system.
