EPC Material Handling Installation
Virginia
Scope
of work included engineering, procurement, and construction of Fly
Ash, Bed Ash, Coal, Limestone, and Wood Waste Material Handling
Systems to support a new hybrid electric generating facility rated at
670 megawatts. This hybrid facility will utilize fossil fuels as well
as biomass to produce new electric power.
The
ash handling system included four subsystems comprised of a Fly Ash
System, a Bed Ash System, Ash Storage and Unloading System and a Bed
Ash Re-Injection System. A pneumatic conveying system was designed
and installed to move the ash from two (2) Circulating Fluidized Bed
(CFB) boilers economizer hoppers, the scrubber hoppers, scalping
precipitators, and baghouse hoppers to two Fly Ash Silos. A Bed Ash
Re-Injection System was also be designed and installed to reestablish
CFB boiler furnace bed materials after the completion of shutdown
outages when bed inventory has been drained. The Coal Handling System
was designed and constructed to receive 50 ton-capacity trucks and
transfer coal from receiving hoppers to a vibratory feeder for
separation.
