Thermofluoidodynamic 3D Modelling Of Glass Melting Furnces For Combustion Optimisation And Emission Reduction

This paper reports recent results in the domain of mathematical simulation of industiral combustion, developed by ENEL Ricera and STARA Glass, working on two typical U- and natural gas-fired glass melting furnaces, the first with a glass production of 90 tonnes/day and the second 200 tonnes/day. A 3D model for computational fluidodynamic (CFD) simulations of these furnaces was then developed, and the experimental data were used for model validation on real scale. CFD results were then used for reactor network analysis and to study NOx emissions with detailed chemical kinetic models.
