Tube conveyor for dry ash removal system
TAKRAF has delivered the complete residual material handling and disposal system including:
- Long distance material transport with tube conveyor
- Transfer tower to feed the dumping system or the emergency stockpile
- Dumping system with shiftable conveyor, tripper car and stacker
- Emergency stockpile with radial stacker
Tube conveyors are very common in residual material transportation due to the encapsulation of the material. Special feature of this project is the ambient temperature of minimum -45 °C combined with a material temperature of maximum 90 °C at the tube conveyor feeding point.
The tube conveyor is running in five horizontal curves with 420 m to 630 m radius. To ensure the correct overlap position at the discharge area the patented belt training system (BTS) is used.
