Thermal power plant logistics From the coal handling plant to the boiler bunkers, which material handling equipment is most commonly used to transport coal continuously?

Introduction / Context:
Efficient fuel handling is essential in thermal power stations. Coal must be moved reliably from unloading points to stockyards and onward to boiler bunkers. The choice of equipment balances capacity, continuity, safety, and operating cost.

Given Data / Assumptions:

• Large, continuous throughput is required (hundreds of tonnes per hour).
• The path from coal handling to bunkers is generally fixed and long.
• Equipment must operate continuously with minimal manual intervention.

Concept / Approach:
Belt conveyors provide steady, continuous transport over long distances with gentle handling and high capacity. They integrate well with crusher houses, transfer towers, and tripper systems that distribute coal into multiple bunkers. Alternative equipment like bucket conveyors or cranes is typically used for intermittent or vertical lifts, not for long continuous runs.

Step-by-Step Solution:
Assess need: continuous, high-capacity movement.Match technology: belt conveyor best fits long, fixed routes and high tonnage.Confirm plant practice: tripper or shuttle conveyors commonly feed multiple bunkers.

Verification / Alternative check:
Typical plant layouts show conveyor galleries bridging CHP to boiler house bunkers, confirming industry standard practice.

Why Other Options Are Wrong:
Bucket conveyors are for short vertical transfers; cranes and forklifts are intermittent and labor-intensive; pneumatic tubes are unsuitable for coarse bulk solids like coal.

Common Pitfalls:
Underestimating dust control, belt cleaning, and fire detection requirements along the conveyor route.

Final Answer:
Belt conveyor
