- Project: Coal Unloading and Handling System
- Location: Comanche Station Unit 3, Pueblo, Colorado
- Scope: Engineering, Procurement and Construction
Project Background
The coal handling system is designed to receive coal from trains at the rapid discharge rail unloading facility.
The received coal is transferred to either a new stacking tube with a storage pile capacity of 40,000-tons or to the existing stacking tube. The unloading and stockout rate is 4,000 TPH.
The coal is reclaimed from the new storage pile by four variable rate belt feeders located under the pile.
The coal can also be reclaimed from the storage pile by an emergency hopper/belt feeder located at the edge of the pile.
The two reclaim-conveyors each have a reclaim rate of 1,500 TPH.
At the crusher building the coal is crushed by two 1,500 TPH crushers before being transferred on dual conveyors to the plant transfer tower.
All areas of the coal handling system are provided with bag house dust collection or wet dust suppression.
Ancillary systems include sump pumps and service air.
