| 摘要 |
<p>A process is described that removes by chemical oxidation the excess ammonia (NH3) gas from flue gas that have been subjected to selective catalytic reduction (SCR) and selective non-catalytic reduction (SNCR) of oxides of nitrogen (NOx) by ammonia injection. Methods for the removal of residual ammonia from flue gas prior to fouling air pre-heaters or deposition on fly ash are discussed.</p> |
