ABSTRACT:
A method for operating a combustion system to facilitate reducing emissions from the system is provided. The method includes supplying an aqueous selective reducing agent from an aqueous selective reducing agent source to an atomizer that is directly coupled in flow communication with the aqueous selective reducing agent source. The method also includes atomizing the selective reducing agent in the atomizer, and injecting atomized droplets of the selective reducing agent from the atomizer directly into a transport stream of flue gas flowing within a temperature zone defined within the combustion system.
