Mt Piper Power Station Coal Handling Plant, New South Wales
Working to a performance specification the project team undertook the design and construction for all engineering disciplines of the complete coal handling plant to feed the 2 x 660MW unit power station.
FEATURES:
Project features included:
- completely automated receival facility for road transported coal
- 4,000t capacity surge bin for coal deliveries into the plant from road trucks and overland conveyors, 200t capacity check weigh bin for commercial certification of belt weighers controlling and totalling coal flow throughout the plant
- sampling systems for coal deliveries and on conveyors to the boiler bunkers
- crusher building housing four 660t/h double roll sizers
- dry storage shed covering a 35,000t live stockpile serviced by automatic rail mounted stacker and portal reclaimer
- long term 600,000t compacted stockpile with two dozer reclaim facilities
- belt conveyors totalling in excess of 4,200m total length operating at 2,500t/h for receiving and stockpiling and at 1,200t/h for delivering coal to the bunkers. The conveying system makes extensive use of shuttle-head technology for reduced height transfers and flexible operation. To ensure coal supply to the boilers the delivery conveyor system is duplicated in a duty/standby configuration. Final delivery of coal into the bunkers is by two travelling trippers with on-board dust collection. Dust collection is provided at all coal transfers across the plant
- fire systems complete with deluge systems at coal transfers and wash-down facilities across the plant.
The plant is fully automatic, with custom-designed PLC programming along with all hardwired electrical power and control systems.
BENEFITS:
The single interface/single responsibility performance contract ensured all requirements were met fully on time and within budget with a high level of client satisfaction. The plant continues to operate at low operational cost and very high reliability.
