Abstract:
1. A method for burning whole tires in a kiln, comprising: providing a kiln having an inlet end, a discharge end and a burning zone there between; providing a cement clinker feedstock at the inlet end; rotating the kiln so that the feedstock works its way toward the discharge end; providing a device for propelling whole waste tires in line with the kiln and displaced a first predetermined distance from the kiln discharge end, the device comprising: feeding the tire into the device; driving at least two of the plurality of associated rotatable elements at differing velocities at the same time so that the tire is accelerated to its final exit velocity as it is propelled along the lower and upper assemblies by contact with the associated rotatable elements at least two of which have differing velocities; propelling the tire from the device across the first predetermined distance and into the kiln discharge end so that the tire lands within a predetermined region within the burning zone; and burning the tire within the kiln.
