Abstract

L'invention concerne un procédé de dénitruration catalytique sélective ou d'utilisation de gaz de combustion contenant des poussières, selon lequel un dispositif de traitement (catalyseur, chaudière à récupération ou échangeur thermique) parcouru par un gaz de combustion contenant des poussières est protégé contre les dépôts de poussières, le dispositif de traitement présentant des zones de surface entrant en contact avec les gaz de combustion contenant des poussières. Les poussières contenues dans le gaz de combustion sont chargées électrostatiquement avant de parcourir le dispositif de traitement et les zones de surface entrant en contact avec les gaz de combustion contenant des poussières sont maintenues à un potentiel aligné sur le potentiel des poussières chargées.
