Schenck AccuRate has received the second annual Whitewater Environmental Achievement Award for the design and manufacture of its alternative fuel-feeding system. 

The University of Wisconsin-Whitewater and the City of Whitewater, Wis., created the award for individuals and companies that have implemented programs to uphold environmental sustainability. Schenck AccuRate is based in Whitewater.

Schenck AccuRate’s alternative fuel-feeding system lowers the emissions of greenhouse gases produced from the use of fossil fuels in cement manufacturing processes. The system has the ability to meter waste materials such as PET bottles, saw dust, tires, paper, wood chips, rice, bone meal and others materials to the main burner and calciner of a cement kiln, thus reducing the need for non-renewable fossil fuels such as coal. Using the system to replace only 5 tons per hour of fossil fuel, 24 hours a day can add up to the equivalent of removing nearly 20,000 cars from the road annually.    

The emissions-lowering system consists of a docking station with live bottom bin for semi-trailers, a chain conveyor, weighfeeder, blow-through rotary feeder, rotary piston blower, pneumatic conveying line and measuring, control and supervisory electronics for continuous operation. The semi-mobile system features a small footprint and can be set up on virtually any firm surface where a truck can drive. The system can be placed next to the cement 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 material to the cement kiln. Accuracies of ±1% within a range of 1:20 and feed rates from 0.25 to 10 tons per hour help produce an even and pulsation-free conveying of fuel through the blow-through rotary feeder.
