Boiler Ash Handling & Recovery System

Boiler Ash Handling & Recovery System – Derrick HI-G® Dewatering Machine

Boiler ash handling and recovery system is designed to remove unburned carbon (char), ash, grit and sand from waste water discharged from wood and bark power boiler. Slurry, composed of water and solids, is sent from the wet precipitator to the Derrick HI-G® Dewatering Machine at rates from 800 to 2200 GPM. The HI-G Dewatering Machine uses two, low horsepower, vibrating motors to apply a high G-force on the urethane screen panels.  This separates the water from the solids.

The unburned carbon, or char, is discharged from the HI-G Dewatering Machine onto a belt conveyor.  It is also stacked on grade for transfer to the bark or waste wood storage area for re-burning in the boiler. The ash, grit and sand is removed for disposal in a land fill.

This type of ash handling and recovery system can be also be used to remove minerals and other solids from process and cooling water streams.
