Comprehensive Checklist for Coal Handling Plant Equipment

A coal handling plant (CHP) plays a critical role in the efficient operation of thermal power stations and industries relying on coal as fuel. Proper maintenance and inspection of CHP equipment ensure smooth operations, minimize downtime, and enhance safety. Below is a detailed checklist covering essential equipment in a coal handling plant.

1. Conveyor Systems
Conveyors are the backbone of coal transportation within the plant. Regular inspections should include:
– Belt alignment and tension checks
– Roller and idler condition (wear and tear, lubrication)
– Drive pulley and tail pulley inspections
– Belt splicing integrity
– Safety devices like pull cords, belt sway switches, and emergency stops

2. Crushers and Breakers
Coal crushers reduce the size of coal for efficient combustion. Key inspection points:
– Check for abnormal vibrations or noise
– Inspect hammers, liners, and grinding elements for wear
– Lubrication levels in bearings and gearboxes
– Clearance adjustments between crushing surfaces

3. Vibrating Screens
Screens separate coal by size before processing. Maintenance checks should cover:
– Screen mesh condition (tears or blockages)
– Motor vibration levels and alignment
– Spring mounts and damping systems

4. Stacker-Reclaimers
These machines stack coal into piles or reclaim it for feeding into conveyors. Inspect:
– Boom movement mechanisms (hydraulic/pneumatic systems)
– Bucket wheel or scraper condition
– Travel rail alignment and wheel wear

5. Dust Suppression Systems
Coal dust poses fire hazards; dust suppression systems must be checked for:
– Nozzle functionality in spray systems
– Water pressure levels in suppression units
