Dynamic modelling for sludge combustion control
Résumé
This paper deals with the design of a model of sludge combustion in a circulating fluidized bed (CFB) furnace to be further implemented in an advanced control law. The transient behaviors of the temperature and the flue gas concentration are predicted. The emphasis is put on the choice of the chemical reactions based on (phisco-chemical) considerations. This model includes dynamic rates of sludge combustion reactions, which are tuned considering literature references and experimental apparatus. The simulation results are realistic and the model can now be improved to include more complex hydrodynamics modeling.
