Selective Catalytic Reduction (SCR)

Cleaver-Brooks’ Selective Catalytic Reduction (SCR) system 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. SCR works with firetube, industrial watertube, heat recovery and retrofit boiler applications.
