Abstract

To reduce their nitrogen oxide content, flue gases from burners are catalytically treated with ammonia vapour, which is fed to the flue gases via a carrier air stream. If ammonia water is used instead of pure ammonia, the water fraction must also be evaporated. Solids, which are obtained as solid residues in evaporation can be dissolved in the ammonia water. In order to avoid the separation of a solid residue stream from the process, the ammonia water is partially evaporated, the vapour formed is swirled in a hot carrier air stream and the remaining liquid is distributed in the carrier air stream with a propellant. By this means the solid residues produced in the form of fine- grained aerosols are discharged without problems in the carrier air stream. <IMAGE>
