Abstract
A process is described that removes by chemical oxidation the excess ammonia (NH) gas from flue gases that have been subjected to selective catalytic reduction (SCR) and selective non-catalytic reduction (SNCR) of oxides of nitrogen (NO) by ammonia injection. Methods for the removal of residual ammonia from flue gases prior to fouling air pre-heaters or deposition on fly ash are discussed.
