For this purpose, an excess of

ammonia is injected and this ammonia-enriched flue gas stream is first passed over aknown reduction catalyst (12) and then over an oxidation catalyst (13) for oxidising theremaining ammonia excess. The catalyst arrangement according to the invention isespecially suitable for use in an industrial combustion installation.
