Selective Catalytic Reduction (SCR) is a post-flue gas

2018-8-5 · CFD modeling used to optimize every system; Works with Firetube, IWT, HRSG, and retrofit boilers; Selective Catalytic Reduction (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%.

Indeck Selective Catalytic Reduction System (I-SCR™)

Indeck’s engineering team designed the Indeck Selective Catalytic Reduction (I-SCR) system to meet the most stringent requirements for emission control. Indeck’s selective catalytic reduction process converts combustion flue gas nitrogen oxide (NOx) emissions into harmless nitrogen (N2) and water (H2O) without forming secondary pollutants.
