Following homogenization, the contaminated material is introduced into the reactor's preheating zone, where water is evaporated off and the solid matter is heated by exchange with inert oxidized solids taken from the combustion zone. The material is then sent to the combustion unit where the energy is recovered. The system allows heat recovery from solids as well as from liquid and gaseous effluents. All the combustion and exhaust gases from the reactor are channelled toward a battery of series of cyclones, sleeve filters, damp purification and activated charcoal adsorption systems. If metals are present in the material to be treated, some may end up in dust and smoke treatment residues.
Treated soils are usable as landfill or for civil engineering works.
The treatment systems for liquid and gaseous effluents are integrated into the technology and ensure that current norms are respected. The technology is equipped with a computerized instrumentation system. The organic compound concentration of the reactor's output is below detectable limits. At the present time, the size of entering particles is limited to 70 mm. The kiln, which has a 3 m diameter and 8.5 m length, is installed on a 30 x 40 m platform.
