Abstract

I en fremgangsmåte for fjerning av dannet røkgass i termiske avfallsanriking blir vandig ammoniakkoppløsning innfbrt i etterreaksjonsrommet i forbrenningsanlegget. For å unngå ammoniakkresler blir den rensede rekgassen fjernet for nitrogen ved hjelp av en fastkatalysator.In a process for removing formed flue gas in thermal waste enrichment, aqueous ammonia solution is introduced into the after-reaction space of the combustion plant. In order to avoid ammonia pellets, the purified extract gas is removed for nitrogen by means of a solid catalyst.
