Abstract

Chaudière de récupération de chaleur, comportant un appareil de dénitration. Elle comprend plusieurs étages, par exemple un surchauffeur 4, un évaporateur 5 et un économiseur 6 disposés dans le circuit des gaz de combustion. Une couche 20 de catalyseur de dénitration est montée entre deux de ces étages, par exemple entre le surchauffeur 4 et l'évaporateur 5, de même qu'un dispositif 21 qui introduit de l'ammoniac comme agent réducteur dans les gaz de combustion, en amont de la couche 20 de catalyseur. Cette dernière comprend un certain nombre de plaques dont les surfaces planes sont orientées dans la direction d'écoulement des gaz et forment avantageusement une structure en nid d'abeilles. Domaine d'application : chaudières de récupération de chaleur.
