Selective Catalytic Reduction System definition

Selective Catalytic Reduction System or “SCR” means a pollution control device that employs selective catalytic reduction technology for the reduction of NOx emissions.
Sample 1Sample 2Sample 3
Selective Catalytic Reduction System or “SCR” means an air pollution control device for reducing NOx emissions in which ammonia (NH3) is added to the flue gas stream and then passed through layers of a catalyst material. The ammonia and NOx in the flue gas stream react on the surface of the catalyst, forming nitrogen (N2) and water vapor.
