Abstract
The effects of steam addition into the oxidizer on combustion behaviours of coke oven gas has been numerically investigated within the present study. Ansys Fluent that is a commercial computational fluid dynamics code has been used in the study. The predictions in which air have been used as oxidizer have been compared with the experimental results and it has been determined that the predicted results are in good agreement with them in terms of trends and values. k-Ɛ standard turbulence model has been selected as turbulence model, the PDF/Mixture Fraction combustion model and P-1 radiation model have been used for three-dimensional modellings. According to the predicted results, it has been revealed that steam addition into the oxidizer has decreased the predicted temperature values of coke oven gas. When the results are evaluated in terms of emissions, it has been found out that steam addition into the oxidizer has increased CO emissions somewhat while it has decreased NOX emissions considerably and CO2 emissions somewhat. Therefore, it has been concluded that high NOX problem caused by the use of coke oven gas being an alternative fuel can be overcome via steam addition into the oxidizer.
