Claims (10)

1. Anlæg (10) til katalytisk denitrifikation af røggasser, omfattende: - en denitrifikationsreaktor (12), som indeholder en struktureret katalysator (14), hvorigennem der strømmer de røggasser (1), der skal behandles, for at denitrificeres, - en omledningskanal (16): - som er forsynet med mindst ét spjæld (24, 26), - som er monteret ved denitrifikationsreaktoren, og således forbundet dermed, opstrøms for katalysatoren (14), gennem en indgangsåbning (20), - hvorigennem de røggasser, der skal behandles, passerer uden om denitrifikationsreaktoren uden at strømme gennem katalysatoren, når spjældet eller spjældene er åben/åbne, og - midler (30) til rensning af katalysatoren, som er indrettede til at lede en fluid (2) ind i reaktoren for at frigøre støvpartikler (P) fra den frie opstrømsflade (14A) af katalysatoren, kendetegnet ved, at rensningsmidlerne (30) er indrettede til at lede fluiden (2), både tangentielt ved den frie opstrømsflade (14A) af katalysatoren, for at fjerne støvpartiklerne (P) derfra, og til indgangsåbningen (20) af omledningskanalen (16) for at udlede støvpartiklerne gennem denne omledningskanal sammen med mindst en del af de røggasser (1), der skal behandles.
