Diesel has had a rough go of it during the last few years, but an increasingly commonplace technology is working to change the fuel's image and make diesel vehicles viable for the future. Kyle Hyatt ...

When it comes to reducing the nitrogen oxide (NOx) emissions of diesel-burning commercial vehicles, selective catalytic reduction (SCR) is firmly in place as today’s technology. And these systems are ...

Optimal NO x removal by a selective catalytic reduction (SCR) system requires the inlet gas temperature to remain within a prescribed range. How does a baseload unit meet NO x permit limits when it’s ...

Selective catalytic reduction (SCR) projects often focus on the final NO x emissions levels achieved, but a successful project is about much more than that. Facility owners must consider the complete ...

As a result of the Cross-State Air Pollution Rule (CSAPR) and the Ozone National Ambient Air Quality Standard (NAAQS), utilities such as Duke Energy are faced with the need to achieve further ...

Tightening emissions regulations are forcing power plants around the country to develop an acute awarenes of the design and operational challenges associated with selective catalytic reduction systems ...

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 ...

It drives like a 911, only a negative if you don't like 911s To the uninitiated this might look like a humble Porsche 964. However, its big five-spoke alloys, cavernous cooling vents in its front ...
