Abstract:

 This study investigates the effects of adding steam to the oxidizer on the combustion behavior of coke oven gas through numerical simulations. The analysis used the commercial computational fluid dynamics CFD software Ansys Fluent. The results obtained for the case where dry air was used as the oxidizer were compared with experimental data. The k-Ɛ standard turbulence model was employed for turbulence modeling, while the PDFMixture Fraction combustion model and the P-1 radiation model were used for the three-dimensional numerical simulations. According to the simulation results, adding steam to the oxidizer slightly reduced the temperature of the COG. When assessing the emissions, it was observed that NOX emissions significantly decreased, while CO2 emissions showed a slight reduction. However, CO emissions were found to increase slightly. In conclusion, the study indicates that adding steam to the oxidizer significantly mitigates the high NOX emissions typically associated with using coke oven gas as an alternative fuel.
