The PYRETRON® Thermal Destruction System uses innovative oxygen-air-fuel burners to control the heat input during incineration. The system increases the efficiency over conventional incineration and can be used with either a transportable or fixed rotary kiln incinerator. The PYRETRON system can treat any wastes amenable to incineration, but it is best for the treatment of wastes with low heating values. The PYRETRON burners use the staged introduction of oxygen to efficiently transfer heat to the waste which is fed separately into the kiln. Oxygen, propane, and oxygen-enriched air enter the burner in three separate streams. A stream of pure oxygen is fed through the center of the burner and is used to burn propane in a substoichiometric manner. Combustion is completed by mixing these hot combustion products with the stream of oxygen-enriched air introduced around the outside of the flame envelope. The technology was demonstrated at EPA's Incineration Research Facility using a mixture of soils from the Stringfellow Superfund site and decanter tank car sludge. The technology achieved 99.99 percent destruction and removal efficiency of all the principal organic hazardous constituents (POHC). The POHCs included naphthalene, acenaphthylene, fluorene, phenanthrene, anthracene, and fluoranthene.
