De-NOx system is based on reactions between reductants and nitrogen oxides. KC Cottrell has supplied highly reliable De-NOx systems fitting the diverse needs and situations of our customers throughout the world. We have successfully installed DeNOx systems in Power Plants, Waste to Energy and heavy industries like steel and non-ferrous.
Selective Catalytic Reduction(SCR) process has a reduction reaction at comparatively low temperature using catalysts.
This process shows the highest efficiency and stability in removing nitrogen oxides.
Denitrification or DeNOx system eliminates NOx (Nitrogen Oxydes) by reaction with injection of ammonia or urea based on the following equations:
4NO + 4NH3 + O2 --> 4N2 + 6H2O
6NO2 + 8NH3 --> 7N2 + 12H2O
Selective Non-Catalytic Reduction(SNCR) process happens in a higher temperature (850ºC~1,050ºC) area than SCR.
KC Cottrell guarantees the best performances of SNCR by selecting exact areas to spray reductants based on the simulation of flue gas flow patten.
Catalysts account for a large part of operating costs. Therefore, we developed a technology to regenerate used catalysts.
Regenerated catalysts can show efficiencies more than 90% of new ones while reducing expenses and protecting environments.
