Selective Catalytic Reduction
EcoCAT: Emissions Reduction for Fuel-Fired Systems
Selective Catalytic Reduction (SCR) is a post-flue gas treatment that is capable of reducing NOx emissions from a wide variety of systems.
SCR is one of the most effective ways of reducing NOx in a flue gas stream with reductions in excess of 95%!
- The industry’s only totally integrated system
- Ammonia transforms NOx into harmless nitrogen
- Flow modeling used to optimized every system
- Applications for any fuel-fired equipment
How it Works
SCR uses ammonia as a reducing agent, which is introduced into a flue gas stream.
This mixture then comes in contact with a catalyst, transforming the NOx into harmless nitrogen & water.
