NO emissions from the combustion of evolved gases in wildland fires
Résumé
The aim of this work is to study the NO emissions under typical wildland fires conditions, paying special attention to the effect of the fuel-bound nitrogen. For this purpose, numerical simulations have been run using the PSR code from the CHEMKIN II package with a full mechanism (GDF-Kin® 3.0). Fuel bound-nitrogen has been included in the pyrolysis gaseous mixture of vegetation as NH3. Results have shown that if fuel-nitrogen is not considered on the pyrolysis mixture, NO emissions in wildland fire conditions are strongly under-estimated. Simulations results have been compared to experimental data.
