selective catalytic reduction system for boiler flue gas

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%.

2019-8-30 · The selective catalytic reduction (SCR) removes nitrogen oxides (NOx) from flue gas emitted by power plant boilers and other combustion sources, and the catalyst is the key component of this system.

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.
