NOx emissions on pulverized coal fired (PC) boilers are increasingly being managed through the use of flue gas treatment technologies (i.e. SCR and SNCR); however, opportunities exist for managing NOx by optimizing boiler side or “combustion” side parameters. Optimized combustion includes control and management of the secondary airflow, balancing the primary air and fuel flow to the burners, burner tuning and burner tilts (tangential fired boilers) and pulverizer performance. Managing the combustion inputs should be the first step towards NOx reduction.
