into the boiler flue gas to obtain a specific level of NO X reduction. In the SNCR process, the combustion unit acts as the reactor chamber. The reagent is generally injected within the boiler superheater and reheater radiant and convective regions, where the combustion gas temperature is at the required temperature range. The injection system is designed to promote mixing of the reagent with the flue gas.

Selective Non-Catalytic Reduction - an overview

Selective Non Catalytic Reduction (SNCR) is a well-known method to lower the level of Nitrogen Oxide in flue gas emissions from a boiler system. The system injects a reagent (usually ammonia or urea) at the combustion level of the boiler where the temperature of gas is between 850 and 1050 degrees. The reagent reacts with Nitrogen Oxide produced during the combustion process to produce easy …
