Selective Catalytic Reduction (SCR) Control

Breen Energy Solution offers a comprehensive SCR tuning package that goes beyond traditional tuning protocols. Like other vendors we use O2/NOx measurements to balance NOx concentrations at the SCR outlet grid. However, in addition to that, we also utilize the AbSensor Condensables devices to measure the SO3entering and exiting the SCR, and the presence and severity of Ammonium Bisulfate and therefore Ammonia Slip at the SCR Outlet/AH inlet as well as providing calculations for estimated AbS bulk and capillary dewpoints which determine the SCR Minimum Operating Temperature.

We also offer our services to conduct SCR Enhanced Mode operation and establish operating protocols and Mill Configuration, which will allow you to continue operating the SCR below the vendor MOT curves while ensuring that you can bake off the accumulated AbS after load pickup.
