Selective catalytic reduction (SCR) for NO x removal from utility boilers has been shown to have extremely high removal efficiencies. In recent years, there has been increased focus on a potentially ...

Boulder, Colo., December 10, 2012-AeriNOx (Boulder, Colorado) and its parent company, H+H Environmental Technologies (Hargesheim, Germany), announced today an agreement to supply SCR emission control ...

Modern diesel cars, trucks and SUVs have selective catalytic reduction (SCR) systems to reduce exhaust pollutants and meet emissions standards. These systems work by injecting diesel exhaust fluid ...

A force-commutated SCR makes a novel Solid State Switch in a solar charge regulator control. Prior art includes relay and transistor switches, but an SCR switch in this type of DC application may be ...

SCRs (silicon-controlled rectifiers), or thyristors, have higher current and voltage ratings, lower conduction losses, and more robustness than triacs. For these reasons, SCRs are better suited to ...

SAE International Journal of Engines, Vol. 7, No. 2 (July 2014), pp. 1113-1124 (12 pages) ABSTRACT Various engine platforms employ Selective Catalytic Reduction (SCR) technology to reduce the tail ...

Southwest Research Institute (SwRI) has developed a method to automate the calibration of heavy-duty diesel truck emissions ...
