- Scope: Engineering, Procurement, and Commissioning
Project Background
Roberts & Schaefer Company was awarded a turnkey contract from Sargent & Lundy LLC for engineering, procurement and commissioning of two stacker/reclaimers and a traveling hopper at Huaneng Power International’s Dandong Generating Station in Dandong, China. The system was successfully completed and in operation in 1998.
To stockout and reclaim the coal two stacker/reclaimers were provided. The stacker/reclaimers have a stacking capacity of 1800 TPH and a reclaiming capacity of 720 TPH. The stacker/reclaimer boom is 100 feet long with a 21–foot diameter bucket wheel reclaimer. The machine is capable of slewing a total of 270 degrees and can travel more than 1000 feet over rails. Each machine has an on board control cab and is completely controlled by a programmable logic controller (PLC).
For coal deliveries by self–unloading ships, a traveling hopper located on the dock was provided. The hopper capacity is 155 tons of coal and incorporates four vibratory feeders each of which is rated at 1000 TPH. The vibratory feeders in turn feed dual unloading conveyors, which send the coal through a series of conveyors and transfers to the stacker/reclaimers. The traveling hopper can move over 375 feet on rails. The traveling hopper is equipped with on board PLC and dust suppression systems.
