•Ammonia Inj.: The total mass flow rate of ammonia injected into the SCR. This is a function of the NOx concentration in the flue gas and the ammonia stoichiometric performance input value. •Steam for ...

The process that can convert pollution into benign by-products is called selective catalytic reduction, or SCR. Until now, it has been unclear how this reaction actually occurs, and contradictions ...

Emission regulations for combustion systems have been in place for more than half a century and in the 1990’s, the Clean Air Act put a spotlight on emissions specifically from industrial boilers.

Commercially available technologies for reducing nitrogen oxide (NO x) emissions from coal-fired boilers are enabling industry compliance with today’s regulatory requirements. Low-NO x burners (LNB) ...

The efficiency and long-term performance of an SCR System is largely dependent on several key design considerations of the various equipment within the SCR System. When complex NOx reductions on ...

Today’s workboat operators must navigate increasingly stringent IMO and EPA environmental and emissions regulations in and around ports and rivers. As the drama unfolds, selective catalytic reduction ...

Pollutants emitted from combustion sources have been regulated by local and federal governments since the early 1960s. Specific rules vary by state and air district, but they generally apply to ...

At issue is the question of keeping diesel exhaust fluid in the tank for proper functioning of selective catalytic reduction. Changes to the EPA's 2010 emissions regulations relating to selective ...
