RÉSUMÉ

We intend in this work to simulate numerically an industrial burner of a ceramic tunnel furnace of the Ceramics Modern Society (SOMOCER, TUNISIA). This study aims to evaluate the impact of three different operating modes (air excess, stoichiometric and air deficiency) of the burners on the characteristics of the flow parameters. The study is conducted by means of numerical simulations in reactive flow using the FLUENT commercial code. The turbulent RSM model coupled with the turbulent combustion ED model (Eddy-Dissipation) and DTRM model (Directe Transfer Radiation Model) are used to model respectively turbulence, combustion and radiation. The results obtained for different operating burner modes prove that on one hand, the structure of the flow is practically the same; on the other hand, the gas flow rate has no influence on the shape of the flame but has an impact on its color and temperature.
