摘要
We intend in this work to model an industrial burner replica of the ceramic tunnel furnace of the Ceramics Modern Society (SOMOCER, TUNISIA). This study aims to investigate numerically the problem of NOx pollution by providing the influence of different operating conditions on temperature and NO distributions. The study is conducted by means of numerical simulations in presence of a reactive flow using the commercial code FLUENT. The 3D Navier-Stokes equations and species transport equations are solved with the eddy-dissipation (ED) combustion model. We use k-epsilon RNG turbulence models and the DTRM radiation models. The obtained results demonstrate that the combustion chamber average temperature and NO concentration decrease as the excess air factor increases for to given air mass flow. As the combustion air temperature increases, combustion chamber temperature. increases and the NO concentration increases sharply.
