Catalysts used in selective catalytic reduction (SCR) systems in utility boilers provide high NOx removal efficiencies that routinely exceed 90%. A major co-benefit of applying SCR to coal-fired ...

SCR process design for the latter applications provide for unit-specific NO x limits of approximately 100 ppm, about equivalent to the 0.15 lb/MMBtu required by the SIP Call.

"Inducement" is a word that is getting much play in the Selective Catalytic Reduction debate right now. What are inducements? Let's step back and consider the SCR process. The diesel engine ...

A zirconium oxide sensor technology originally developed for automotive applications could make in situ, simultaneous measurement of O2 and NOx a breeze for coal-fired power plants.

Diesel exhaust fluid or DEF is a critical ingredient for making selective catalytic reduction (SCR) work. It's a clear fluid with a very slight yellowish tinge to it and smells faintly of ammonia ...
