Low Failure Rate in High Dust Environments: TD75 Fixed Conveyor for SEA Thermal Power Plants

2026-06-25

1. Conveying Pain Points of Dust Conditions in SEA Thermal Power Plants

Thermal power plants across Southeast Asia mainly burn raw coal as fuel. High dust fills coal feeding yards, stockpiles and transportation corridors all year round. Fine coal powder generates massive dust. Ordinary conveyors running for long hours easily suffer from jammed idlers covered with coal dust, accelerated belt abrasion and bearing failure caused by dust ingress. Frequent shutdowns for maintenance disrupt coal supply to boilers and interfere with stable unit load output. In addition, high temperature mixed with dust corrosion shortens the service life of conveyor parts and raises long-term maintenance costs.

2. Parameter Analysis of TD75 Fixed Belt Conveyor for Dusty Power Plant Conditions

Original TD75 technical parameters fit harsh coal conveying scenarios, and its structure can be optimized for dust prevention. Key hardware indicators are listed below:

Operating temperature range: Ambient temperature -10℃ to +40℃, maximum allowable material temperature 50℃, suitable for both indoor coal corridors and open coal yards of SEA power plants;
Full range of conveying specifications: Belt width 500–1400mm, belt speed 0.8–5.0m/s, peak capacity 4130m³/h, meeting the continuous coal supply demand of power units;
Idler structural design: Standard 30° and 35° trough idlers contain coal dust to reduce dust diffusion and lower the risk of dust entering bearings;
Custom dust-proof accessories: Full dust covers and sealed bearing assemblies are optional to avoid component jamming caused by accumulated coal dust and cut failure risks.

3. Core Selection Standards of Conveyors for SEA Thermal Power Plants

Energy purchasers should check three key indicators for stable operation during equipment selection:

Dust-proof upgrade compatibility: Support fully enclosed dust-proof structures for long-term high coal dust working conditions;
High-volume continuous conveying performance: Multiple belt widths and speeds to match coal transport lines of different power generation capacities;
Wear-resistant sealed component layout: Trough idlers with sealed bearings reduce maintenance downtime triggered by dust erosion.

4. Industry Conclusion

To tackle the high failure rate issue under heavy dust conditions in Southeast Asian thermal power plants, the TD75 fixed belt conveyor ensures steady long-term operation of coal handling systems with wide temperature tolerance, high throughput and customizable dust-sealed structures. It minimizes equipment shutdowns caused by dust and maintains consistent material supply for power generating units.
