Modélisation d'un incinérateur de boues en lit fluidisé en vue de la maîtrise des émissions de NOx

Abstract : Sludge incineration in fluidised bed is a very complex process, producing gaseous pollutants (carbon monoxide (CO) and nitrogen oxides (NOx)). The legislative norms need to be respected despite of variations of sludge in composition and in quantity. An oxygen regulation guarantees CO norm but not NOx norm. The NOx formation, due to lots of chemical reactions from the sludge nitrogen, is partly unknown. A model predicting the NOx emissions has been proposed. Literature study leads to neglect the solid reactants, simplifying greatly the hydrodynamics and the number of chemical reactions. The model has been validated with industrial data. The simulation results validate the simplification hypotheses, but need the reconstruction of sludge composition. A control strategy implemented further next guarantees the legislative norm of NOx.
