About
EcoCAT TM
R.F. MacDonald Co.’s EcoCAT™ Selective Catalytic Reduction (SCR) system uses a patented post-flue gas treatment capable of safety and efficiently reducing NOx emissions for a wide-variety of boiler systems. SCR is one of the most effective ways of reducing NOx in a flue gas stream with reductions in excess of 95% and down to 2 PPM!
- The industry’s only totally integrated system
- Reduce NOx above 95%, down to 2 PPM
- Ammonia turns NOx into harmless nitrogen
- Flow modeling is used to optimize systems
- Applications for any fuel-fired equipment
- Total engineering & installation support
- Achieve higher turndown capabilities
- Achieve sub 5 PPM ammonia slip
- Reduce ammonia vaporizer costs
- Reduce electrical load costs
How it works.
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 2 PPM. It’s a viable option to meet current or future environmental regulations or your company’s sustainability goal. SCR is the most effective method of NOx reduction, as it does not sacrifice performance, unlike other NOx reduction technologies.
