R. Bilbao et al., SIMPLIFIED KINETIC-MODEL OF THE CHEMISTRY IN THE REBURNING ZONE USINGNATURAL-GAS, Industrial & engineering chemistry research, 34(12), 1995, pp. 4540-4548
A simplified kinetic model of the chemistry of NO reduction by the act
ion of natural gas has been obtained. This model consists of 87 elemen
tary reactions and 38 chemical species. It takes into account the natu
ral gas decomposition and oxidation, the interaction between NO and hy
drocarbons, and the conversion of the intermediate nitrogenous species
. The concentrations of the species calculated with the model have bee
n compared with those obtained experimentally using the operating cond
itions for which a good efficiency in the reburning zone is achieved.
The comparison between the theoretical and experimental data of NO, HC
,N, CO, and CO2 has been extended to the results obtained over a wide
range of values of the operating conditions in the reburning zone.
