Reduction of NO emissions from a VOC recuperative incinerator by dilution of the fuel supply
Résumé
This work demonstrates the possibility of reducing NO emissions from an ''in vein'' gas burner using a simple and easy to operate technique: the addition of air or of an inert gas to the burner fuel gas feed. A reduction by 30% can be obtained with air; more than 60% of NO can be avoided using an inert gas. Several interpretations are proposed to explain the observed reductions in NO emissions. By running the burner at a high load and using the technique of fuel gas dilution, both CO and NO emissions can be efficiently lowered.
