A dry bottom ash handling system contemplates a plurality of hoppers disposed beneath a solid fuel-fired steam boiler. Each hopper includes angled walls converging at a generally rectangular opening controlled by a grate door. Air inlets are provided at intersections between adjacent angled walls to (1) facilitate combustion of unburned fuel in the storage hopper, and (2) facilitate flow of ash through the hopper opening. Ash flowing through the hopper opening enters a crusher and is then conveyed via a vacuum line to a point of disposal including a mobile tank truck that receives heavier ash particles and allows bypassing of lighter particles to a silo.

Dry bottom ash handling system

A truck is parked adjacent a coal boiler ash recovery unit and includes a first inlet pipe provided to receive ash from the recovery unit and an outlet pipe provided to convey dust from within the storage chamber of the truck to a bag house where the dust is loaded onto another truck. Water spray may be provided within the storage compartment of the first-mentioned truck to moisten the captured material to reduce dusting.
