SCR Tuning

CleanAir has worked with both utility boiler owners and selective catalytic reduction (SCR) system vendors on several SCR installation projects to characterize SCR system performance. As part of a typical SCR performance test program, the NOx removal efficiency, inlet and outlet NOx distribution, inlet temperature and velocity distribution, ammonia (NH3) slip, SO2 to SO3 conversion, SCR and catalyst pressure drop are determined to demonstrate compliance with SCR performance guarantees.
