Abstract(s) :

(Anglais) Flameless combustion is a technology that meets the criteria of reducing pollutants and increasing efficiency in the field of energy production. Such combustion regime is also characterized by a large fuel flexibility. The present work aims at the validation of a reduced NO mechanism on a flameless furnace fed with Coke Oven Gas. Given the high H2 content of this fuel, including the unconventional NO formation routes become fundamental in order to correctly predict the NO emissions. The reduced mechanism, derived for the specific conditions of flameless combustion regime, includes all the relevant NO formation pathways including thermal NO as well as N2O and NNH. It has been shown that such reduced mechanism performs much better than the global schemes traditionally employed to assess the NO emissions of such systems. In particular, the error is doubled when the global schemes are employed to assess the NO emissions for all the different cases analysed.
