Nitrogen oxide reduction 

SNCR procedure (selective non-catalytic reduction)
In order to meet the increasingly stringent requirements for air pollution control, the SNCR process (selective non-catalytic reduction), among other things, was developed for the denitrification of exhaust gases. A reducing agent (ammonia, urea or urea solution) is purposefully introduced into the hot exhaust gas stream via injection lances or nozzles, thus causing a selective NO reduction. In practice, the temperature window is between 850 and 1100°C. Low investment costs, direct spraying into the boiler and quick retrofitting speak in favour of this technology.
