Claims (3)

1. Rökgasanläggning, vilken omfattar en insprut-ningsanordning (7) för ammoniak och en katalysatoranord- 5 ning (8) för minskning av kväveoxider i närvaro av ammoni-ak och syre, varvid i rökgasanläggningen (2) i strömnings-riktningen efter insprutningsanordningen (7) anordnats ett första katalysatormaterial (12) för reduktion av kväveoxider och ett andra katalysatormaterial (13) för oxidati-10 on av ammoniak i närvaro av syre, kännetecknad därav, att det första katalysatormaterialet (12) är anord-nat i ett första katalysatorblock, som i strömningsrikt-ningen ligger före ett andra katalysatorblock innehällande det andra katalysatormaterialet (13), och att det andra 15 katalysatormaterialet (13) bestär av en molybdenblandoxid-katalysator.
2. Rökgasanläggning enligt patentkravet 1, kännetecknad därav, att vid användning av en reduk-tionskatalysator bestäende av oxiderna TiC^, v2®5» M0O3 20 eller WO3 för kväveoxid har andelen molybdenoxid i bland- katalysatorn höjts.
3. Rökgasanläggning enligt patentkravet 1, kännetecknad därav, att i insprutningsanordningen (7) används högst ett 15 %:igt ammoniaköverskott för att 25 fullständigt reducera kväveoxiderna.
