Abstract

Highlights: The performance of different configurations of burners was investigated. Numerical simulation has been provided and validated regard to measured temperature. Realizable k-ε model was chosen due to result agreement to experimental data. By considering the radiation effect, the numerical results were improved 33%. The configuration, three down-three up, has shown the best temperature uniformity. Abstract: In order to obtain the most uniform temperature of the load, heat transfer in heat treatment furnaces used in the steel industry was studied. Different two-equation turbulence models were compared with experimental results. The Realizable k-ε model, predicts the load center line temperature better than the other two models, and it agrees closer to the experimental data. Also, by considering the radiation effect in the numerical simulation, the results were improved by 33% compared with experimental data. Finally, from different configurations of the burners studied and the results showed that the best temperature uniformity would be achieved for the configuration when the burners were located in a three down-three up arrangement.
