Selective Catalytic Reduction, or SCR, is a post-ﬂue gas treatment that is capable of reducing NOx emissions from a wide variety of boiler systems. SCR is one of the most effective ways of reducing NOx in a ﬂue gas stream, with reductions up to 95%.
SCR uses ammonia as a reducing agent, which is introduced into the ﬂue gas stream. This mixture then comes in contact with a catalyst, selectively transforming the NOx into harmless nitrogen and water. With the addition of SCR, NOx emissions can be reduced down to 1 ppm. It’s a viable option
to help meet current or future environmental regulations or your company’s sustainability goal.
