Selective noncatalytic reduction definition

Selective noncatalytic reduction means a noncombustion control technology that destroys NOx by injecting a reducing agent (e.g., ammonia, urea, or cyanuric acid) into the flue gas, downstream of the combustion zone that converts NOx to molecular nitrogen, water, and when urea or cyanuric acid is used, to carbon dioxide.

Selective noncatalytic reduction or “SNCR” means a noncombustion technology that reduces NOx emissions without a catalyst by injecting a reducing agent (such as ammonia, urea or cyanuric acid) into the flue gas, downstream of the combustion zone; the injection of the reducing agent converts NOx to molecular nitrogen, water, and (if the reducing agent is urea or cyanuric acid) carbon dioxide (CO2).

Selective noncatalytic reduction means a noncombustion control technology thatdestroys NOx by injecting a reducing agent (e.g., ammonia, urea, or cyanuric acid)

Examples of Selective noncatalytic reduction in a sentence

• Selective non-catalytic reduction (SNCR) requires a temperature window that is higher than the exhaust temperatures from utility gas turbine installations.

• SCR has been demonstrated to be able to achieve NOx emission limits of 2.0 ppm.18 Selective non-catalytic reduction (SNCR): Selective non-catalytic reduction involves injection of ammonia or urea with proprietary conditioners into the exhaust gas stream without a catalyst.

• Selective noncatalytic reduction technologies use a reducing agent to reduce the nitrogen oxides to nitrogen and water (EIIP, 1995a; EIIP, 1995b).

• Selective non-catalytic reduction and selective catalytic reduction aim at reducing emissions of nitrogen oxides (NOx), and may have a positive effect on mercury removal by enhancing oxidation of elemental mercury to divalent forms.

• TasWater has provided the Commission with details of both the historical cash distributions made to councils by the three former water and sewerage corporations as well as TasWater’s forecasted cash distributions to 2013-14 and 2014-15.

• Selective non-catalytic reduction systems (“SNCR”) are operational on units 1, 2, and 3 at the Dickerson power plant to control NOx emissions.

• With time, the courts saw waiver clauses increasingly critically, see for example Greenwood v Leather Shod Wheel Company [1900] 1 Ch. 421.

• Within a few months of the war’s end, Sri Lankan Army soldiers were nominated by the Government for peacekeeping duties, and were deployed by the United Nations to Haiti.

• Selective noncatalytic reduction systems have a narrow window of operating temperatures, which can limit their use and their effectiveness, although they have shown promise in combination with SCR systems (Emissions Advantage LLC, 2005).Lean NOx catalyst (LNC) systems are relatively costly, roughly $15,000-$20,000, and provide NOx reductions between 10 and 25 percent (Emissions Advantage LLC, 2005; EPA, 2007).
