A Coal Handling System (CHS) is an integrated system used in industries like thermal power plants, cement plants, and steel industries to receive, store, process, and transport coal efficiently and safely. It ensures a continuous supply of properly sized coal to the required process.
Main Components of Coal Handling System
1. Coal Receiving System - Coal is delivered by trucks, wagons, or ships
- Equipment used:
- Wagon tippler / truck tippler
- Track hopper
2. Feeding System - Controls the flow of coal to conveyors
- Equipment:
- Vibrating feeders
- Apron feeders
3. Crushing System - Reduces coal size to required dimensions
- Equipment:
- Coal crusher (hammer mill / ring granulator)
4. Screening System - Separates coal based on size
- Equipment:
5. Conveying System - Transfers coal from one point to another
- Equipment:
- Belt conveyors
- Screw conveyors (in some cases)
6. Stacking & Storage - Stores coal for future use
- Equipment:
- Stacker
- Reclaimer
- Storage yard / bunkers
7. Dust Suppression System - Controls pollution during handling
- Equipment:
- Water spray system
- Dust extraction units
Applications
- Thermal Power Plants
