Duke/Fluor Daniel
Material Handling System
AES-PR Total Energy Plant
Guayama, Puerto Rico

Duke/Fluor Daniel awarded R&S a turnkey contract to provide the material handling system at the AES-PR Total Energy Plant in Guayama, Puerto Rico. The facility accepts coal or limestone from a self-unloading ship and conveys the material at 3,000 tph to either coal stockpiles or a limestone storage building.

Coal is reclaimed from the stockpiles by ten 400 tph vibratory feeders, conveyed to a crusher building, and reduced by two 720 tph crushers, from 2 inches X 0 to 3/8 inch. The coal is then transported to the boiler building where a tripper fills eight coal silos. Limestone is reclaimed by a 60 tph vibrating feeder and moved via a 36-inch conveyor to the limestone process building.

The facility also accepts aggregate material via a hopper with a 1,800 tph feeder breaker, and transports the material to a ship-loader through a series of conveyors. To facilitate loading, the ship-loader is equipped with a telescopic spout and a retractable boom conveyor.

All unloading, stockpiling, crushing, and shiploading are controlled by a series of programmable logic controllers (PLCs). Additional systems include washdown, sump pumps, and dust collection.
