Project Background
Roberts & Schaefer Company was awarded a turnkey contract from Plum Point Power Partners for engineering, procurement, construction, start–up and commissioning of the coal conveying and dust collection systems at Plum Point Power Partners’ Plum Point Energy Station in Osceola, Arkansas. The systems will be completed in 2009.
The conveying system is designed to receive coal at the rotary car dumper. The received coal is transferred to the first stacking tube to form a 40,000–ton capacity storage pile or transferred to the second stacking tube to form an additional 40,000–ton capacity storage pile. The unloading and stockout capacity is 4,000 TPH.
The coal is reclaimed from the two storage piles by two variable rate rotary plow feeders for a total reclaim capacity of 1,200 TPH. Normally one plow will reclaim from each pile, but the travel distance will allow each plow to reclaim from both piles. An emergency reclaim hopper with a variable speed belt feeder and a separate reclaim conveyor to the crusher building is also provided.
At the crusher building both reclaim conveyors discharge to the surge hopper. The coal is crushed with two 1,200 TPH crushers before being transferred on dual conveyors to the silos at the power plant. Dual conveyors with traveling trippers feed the five silos in a single row.
All areas of the coal handling system are provided with bag house dust collection or wet dust suppression. Both as–received and as–fired sampling systems are provided.
