NOTES:
-
Chipper: approx. 400HP, Diesel fuel consumption:
approx. 30 gal/hr. Diesel fuel at $3.00/gal.
-
Chipping process and chip handling produces large
amounts of particulate matter (PM) in the form of
wood dust that can
cause serious illness in exposed workers. Wood dust is a
proven carcinogenic (cancer-causing). Chipping
losses, mostly in form of wood dust, are approx.
2% or 2 tons in this example. Only 98 tons of
wood chips are deposited into the landfill.
-
Air Curtain Burner residual is 3 tons of ash, hauled
by 1 truck, but is usually land-applied on site;
Chipper residual yields no weight reduction, but does provide significant
volume reduction. In this example, waste is hauled
by at least 12 trucks, each carrying approximately 22 cubic yards
or 5 – 6 tons.
-
The
S-220 is a medium size above ground refractory
walled firebox. Larger and smaller models and
trench burners are
also available. See www.airburners.com.
