ALTERNATIVE FUEL
FEEDING SYSTEMS

Cement manufacturers have proven that commercial and municipal waste streams, including shredded plastics, tires, saw dust, paper, cardboard, and other waste materials can provide an economical and environmentally friendly supplement to their kiln fuel supply. These materials are normally delivered in trailer trucks, and need to be accurately metered to the kiln burner. Schenck Process has developed a complete solution for handling these materials from "trailer to burner". Our solution includes all of the components required for this task arranged in a simple, compact package.

The key to the alternative fuel feeding system is its flexibility in handling a wide variety of materials. Because of the day-to-day material changes that are typically associated with feeding secondary fuels, where one day you may feed shredded plastic, and the next day wood chips, you need equipment that can easily accept those changes. Schenck Process provides the flexibility cement manufacturers are seeking with an alternative fuel feeding system that consists of a docking station with live bottom bin for semi-trailers, troughed belt conveyor, weighfeeder, blow-through rotary feeder, rotary piston blower, pneumatic conveying line, measuring, control, and supervisory electronics for continuous operation.





Typical Design Data & Material Properties:
  • Feed rate: 0.25 -5 t/h
  • Accuracy: ± 1% within a range of 1:20
  • Material: Secondary fuel made of commercial waste
  • Grain size: 0 - 50 mm (<1% < 100 mm)
  • Bulk density: 0.1 -0.8 t/m
  • Moisture Maximum 10%
  • Flow properties slightly sluggish, tending to bridge
  • Pneumatic conveying approximately 50 - 100 m distance to burner
