Lay Summary (French)

Lead
Dans le monde, 90 pourcents de l’énergie consommée résulte de la combustion et cette dernière restera la source d’énergie dominante pour les prochaines décennies. L’augmentation massive de la part des énergies renouvelables cause des problèmes de stabilité des réseaux électriques en raison de leur caractère intermittent. Contrairement aux centrales nucléaires ou à charbon, les turbines a gaz sont capables de compenser ces fluctuations rapides de la production. Elles vont ainsi jouer un rôle crucial dans les réseaux de demain du fait de leur flexibilité d’opération, de leur haut rendement et de leurs émissions de CO2 moitié moins importantes que celles des centrales à charbon. Augmenter la flexibilité des combustibles utilisés (gaz naturel, gaz de synthèse riche en hydrogène ou encore gaz issu de la biomasse) tout en garantissant une combustion stable et de très faibles émissions d’oxydes d’azote constitue le grand challenge dans lequel s'inscrit ce projet de recherche.
Lay summary

Contenu et objectifs du travail de recherche

Notre principal objectif est de développer des méthodes pour la prédiction et le contrôle des instabilités de combustion dans un nouveau type de chambre qui équipera les prochaines générations de turbines à gaz. Ce saut technologique se base sur une architecture de combustion séquentielle à pression constante. En particulier, nous allons (i) identifier les mécanismes fondamentaux à l’origine des phénomènes de résonance résultant des couplages non-linéaires entre l’écoulement réactif, l’acoustique du système et les ondes d’entropie, (ii) développer des outils théoriques et numériques permettant de prédire les instabilités de combustion, (iii) valider expérimentalement ces méthodes au moyen de bancs génériques et (iv) développer un système de contrôle actif par plasma froid.

 

Contexte scientifique et social du projet de recherche

Notre travail génèrera des outils théoriques et numériques indispensables au développement et à l’optimisation des chambres de combustion séquentielles équipant les turbines à gaz de demain. Ces systèmes à faibles émissions polluantes procureront une bien meilleure flexibilité en termes d’opération et de combustibles, une puissance et un rendement accrus par rapport aux systèmes modernes ainsi que la capacité à compenser les fluctuations de production inhérentes aux énergies solaires et éoliennes.

Abstract

The proposed research aims at developing a novel theoretical and numerical framework to predict and control combustion instabilities in a new type of combustion chambers for the next generation of heavy-duty gas turbines. This technology step change is based on constant pressure sequential combustion architectures and provides higher fuel and operational flexibility and higher efficiency and power compared to modern single stage combustion chambers. In particular, it will be fuel-flexible and capable of burning conventional gaseous and liquid fuels as well as bio- and syn(thetic)- gas on demand. This research will provide essential tools for sequential combustor development and optimisation. Active control of combustion instabilities in sequential combustion systems using non-thermal plasma will also be investigated at high pressure, which is the first step toward a practical usage of this control technology and which could constitute a further improvement of the constant pressure sequential combustion systems.
