Roberts & Schaefer provided engineering and procurement of
a fuel handling and processing facility, which handles both bituminous
coal and bituminous coal gob. R&S also provided engineering
on the associated silos, and supplied electrical apparatus, control
and instrumentation, and control panels, as well as interfacing
with the owner-supplied control systems.
Twin unloading hoppers handle the material, each rated at a nominal
30 tons. Vibrating feeders reclaim material, which is collected
on a 36-inch fuel transfer belt, rated at 500 TPH. Material is
then transferred to a 60-inch high-angle elevating conveyor using
a flexible belt wall. This unique, special design conveyor is
fitted with a service way for its entire length. Material from
the elevating conveyor discharges to either the coal silo or the
gob silo.
The fuel silos have specially designed, variable-speed rotary
plow feeders, which discharge to twin-way feeders, which in turn
carry the material to either BMR or Hammermill crushers. Crushed
material is collected and conveyed to a second high-angle elevating
conveyor, rated at 120 TPH, for delivery to bunker fuel bins.
The facility includes an emergency hopper, suitable for front-end
loading, and fitted with an en-masse elevating conveyor for emergency
reclaiming.
Restrictions on the project site were extreme, since the facility
is within the city of Morgantown and adjacent to the University
of West Virginia campus. As a result, Roberts & Schaefer provided
construction, shop, and component pre-assembly at nearby staging
areas. R&S completed the project in about 15 months.
