Abstract
Chaudière comportant un appareil de dénitration monté dans le conduit de sortie du gaz de combustion. Elle comporte un appareil 35 de dénitration monté dans une zone présentant une température optimale de réaction pour le catalyseur de dénitration. Le réglage de la température de cette zone s'effectue à l'aide d'un conduit 44 de dérivation sur lequel une soupape 45 de commande est montée. Domaine d'application : dénitration des gaz de combustion.
