First-principles simplified modelling of glass furnaces combustion chambers

To control glass furnaces, advanced techniques like Model-Predictive Control are implemented in tools that allow a multi-objective optimisation of the system operation. In this model-based application, computation time is limited and rapid models are required. The first-principles modelling approach is showing interesting perspectives in comparison to usual black-box models, provided sufficient simplifications are made to lower the computational demand. In this paper, the choice of the modelling approach is discussed and a rapid model of the combustion chamber is presented.
