The increasingly stringent emission requirements put in place by authorities and communities around the country require boiler and turbine operators to reevaluate their emission strategies.
Small and medium-sized boilers are often the foundation for production for smaller and mid-sized companies. Until recently, they have been able to continue operation with only primary types of emission control (e.g., low-NOx burners). These smaller compact boilers often feature a very low exhaust gas temperature less than 400°F, a temperature too low for NOx removal using traditional selective catalyst reduction (SCR).
