Contribution à la modélisation simplifiée des fours verriers

Abstract : Industrial glass furnaces operate the fusion and the preparation of a vitrifiable mixture before the forming. Inside a refractory enclosure, the masses are mixed and undergo the glass elaboration processes thanks to the energy input by combustion. To ensure an optimal quality of the product while respecting the operating constraints, the furnace control is optimized, particularly thanks to predictive control algorithms.For these real-time applications, rapid models of the furnace are required. Among the various simplified modelling methods, we chose here to write the first-principles on a simplified geometry, making simplifying assumptions on the flow structure and combustion model. The model is of zonai type and gives the temperature mean profiles in the furnace. The work was mainly focused on the combustion chamber, and the originality remains in the possibility to tu ne the model thanks to empirical parameters on the combustion rate.
