Description:
The Horsehead Resource Development Company, Inc. (HRD) Flame Reactor is a patented and proven high temperature thermal process designed to safely treat industrial residues and wastes containing metals. During processing, the waste material is introduced into the hottest portion of the Flame Reactor, where the wastes are subjected to a very hot reducing gas (greater than 2000°C) produced from the com- bustion of solid or gaseous hydrocarbon fuels in oxygen-enriched air. At these high temperatures volatile metals in the waste are volatilized and organic compounds are destroyed. The waste materials react rapidly, producing a non-leachable slag and gases, including steam and volatile metal vapors. The metal vapors further react and cool in the combustion chamber and cooling system to produce a metal-enriched oxide that is collected in a baghouse. The resulting metal oxides can be recycled to recover the metals. The amount of waste reduction to slag and oxide depends on the chemical and physical properties of the waste material.
