Notice of RetractionA Novel Concept for Waste Tire Recycles: As Reburning Fuel for NOx Reduction

Abstract

Waste tires are increasing rapidly as solid waste and it's difficult to carry out the management problems associated with the waste tire disposal. The authors briefly reviewed the present recycle technologies for waste tires and the state of art of nitrogen oxide control by reburning. Then the authors proposed the use of waste tires as reburning fuel to reduce NO emitted from coal-fired boilers. The recent research work by the authors were reviewed and the major experiment results showed that a mixed fuel based on waste tire powder and lignite ash and Fe203 can reduce more than 80% of NO. This efficiency is even higher than that by methane reburning. This technology can dispose waste tires at a maximum extent by clean utilization of waste tire as a useful energy resource. This paper has implications for policy makers evaluating solid waste disposal options, as well as for boilers involved in determining appropriate NOx control strategies.
