Abstract: An apparatus and a method fractionate solid fuels, especially whole tires, into metal as well as volatiles and coal to be used as alternative fuels. The apparatus includes a feeding zone wherein the solid fuels are fed to the apparatus, a gasifying zone into which the solid fuels are processed, obtaining a gaseous fraction, coal, and metal; cooled grills controlling the bed permeability and permanence time of the solid fuels at the gasifying zone; and a discharging zone into which the resultant coal and metal are discharged, in which the solid fuel coal and solid and gaseous fractions follow a path inside the apparatus through the feeding zone, the gasifying zone and discharging zone, and in which the gases inside the apparatus follow a path that is co-current with the solid fuel fractions path inside the apparatus.

Abstract: Method and apparatus to recover energy from waste by means of combustion of such waste in industrial furnaces, particularly of the rotary type, that has an external calciner, feeding such waste into the tertiary air duct of the calciner and burning the waste inside the duct itself, to efficiently make use of the energy produced by such combustion, as a contribution of the total cost of fuel necessary to operate the industrial furnace. The method and apparatus permit the elimination of hazardous wastes that are efficiently disassociated when burned sufficiently to produce effluents that are typically non-toxic, producing greatly reduced or even no atmospheric pollution nor environmental damage.
