Tube conveyor at power plant, Maritza East
The tube conveyor was selected to transport residual materials (ash and gypsum) from the power plant to the disposal area by two reasons:
- Environmental friendly transport without influencing material and surroundings
- Conveyor routing following the natural terrain with tight horizontal and vertical curves
The tube conveyor has eight horizontal curves with 350 m to 500 m radii. To ensure the correct overlap position at the discharge area, the patented belt training system (BTS) is used.
