One embodiment described herein relates to a system for removing pollutants from a flue gas. The system includes a selective catalytic reduction (SCR) system having a SCR reactor (22) containing a NOx reducing catalyst and one or more SCR protective devices (20). At least one of the SCR protective devices (20) is connected to a rapping hammer system (24) that actively remove fly ash collected on the SCR protective devices (20).
L'invention porte sur un système permettant d'éliminer les matières polluantes d'un gaz de combustion. Le système comprend un système de réduction sélective catalytique possédant un réacteur (22) contenant un catalyseur réduisant les émissions de NOx et un ou plusieurs dispositifs de protection (20). Au moins un des dispositifs de protection (20) du système de réduction sélective catalytique est raccordé à un système de maillet conique (24) qui élimine activement les cendres volantes collectées sur les dispositifs de protection (20) du système de réduction sélective catalytique.
