7 It is the property of GE and shall not be used, disclosed to others or reproduced without the express written consent of GEThe SNCR process In the SNCR process, NOxmolecules are reduced by either ammonia or urea. Sum of reactions : 4 NO + 4 NH3+ O2 4 N2+ 6 H2O 4NO + 2CO(NH2)2+ O2 4N2+ 4H2O + 2CO2 The process is sensible to:-Temperature and residence time. The reagent must remain at in the correct temperature window (right) long enough, at all boiler loads-Flue gas penetrationby the removalTemperature ( C)No reactionReductionOxidationEffect of temperature on NOxreduction. SNCR reactions best occur between 870 C and 1,150 C.
