Abstract
Waste tires are disposed of in a cement-manufacturing or other mineral-burning process by introducing the tires into the hot gas stream at at least one point between the mineral-inlet end of a rotary kiln and the lowermost cyclone of an associated preheater system, e.g. into the gas stream within a precalciner vessel or riser duct, the tires being maintained in contact with the hot gas for a sufficient period to effect at least partial combustion of the tires. As an alternative, the tires may be introduced into a Lepol grate preheater.
