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.

Moving Bed Gasifier - an overview | ScienceDirect Topics

The Lurgi dry-ash gasifier is a pressurized, dry-ash, moving-bed gasifier. Sized coal enters the top of the gasifier through a lock hopper and moves down through the bed. Steam and oxygen enter at the bottom and react with the coal as the gases move up the bed. Ash is removed at the bottom of the gasifier by a rotating grate and lock hopper.
