Ash Conveyor System
AMH ash conveyor system was engineered and fabricated to handle 500 lbs of boiler bottom ash per hour. The modular bolt-together construction allows for the bottom wear plate to be removed, and return wear rails to be replaced with no field welding. The chain selected for this application was a double strand 14mm x 50mm chain with 18” wide flight bars. This was designed to allow for 10” clinkers to fall out of the bottom of the boiler and through the chain.
Precipitator Conveyor
Fabricated tail end section conveyor was designed and used to move ash under an Electrostatic Precipitator. This conveyor uses 142mm drop forged chain and sprockets, and has a spring loading take-up system.
Chip Screens
These were designed with a double life tooth profile. We worked closely with the mill reliability engineer to design this concept through extensive measurement monitoring. Our design increased the service life while reducing expensive downtime and change out costs. The design is modular, and also allows for the discs to be replaced after the tooth profile wears down.
