Coal Bunker - an overview | ScienceDirect Topics
Crushed coal is sent to the stockyard when coal bunkers are full. Stacking/reclaiming of coal is done by a bucket wheel stacker-cum-reclaimer moving on rails. The stacker-reclaimer stacks coal on either side of the yard conveyor. During stacking operations, the coal is fed from yard conveyors on a boom conveyor.
