The Schenck Process Alternative Fuel
Feeding system for cement manufac-
turers provides the environmentally
friendly solution. Key to the system is
the ability to meter waste materials
such as PET bottles, saw dust, tires,
paper, wood chips, rice, bone meal,
and others to the main burner and cal-
ciner of a cement kiln reducing the
need for non-renewable fossil fuels
such as coal.
Schenck Process offers a modular al-
ternative fuel feeding system that con-
sists of a docking station with live
bottom bin for semi-trailers, chain con-
veyor, weighfeeder, blow-through ro-
tary feeder, rotary piston blower,
pneumatic conveying line, and meas-
uring, control, and supervisory elec-
tronics for continuous operation.
The semi-mobile system features a
small footprint so no special founda-
tions are necessary and can be set up
on virtually any firm surface where a
truck can drive. Placement of the sys-
tem is possible next to the kiln or up to
a distance of 300 ft. from the burner.
Dismantling and reconstructing in any
other part of the plant can be done
within a short period of time.
Critical features of the system include
precise accuracies, a wide range of
feed rates, and consistent flow of ma-
terial to the kiln. Accuracies of ±1 per-
cent within a range of 1:20 and feed
rates from 0.25 to 10 tph help produce
an even and pulsation free conveying
of fuel through the blow-through rotary
feeder.
This consistency and the overall envi-
ronmental impact of the alternative
fuel feeding system make it a logical fit
for cement manufacturing operations,
according to the company.
