Beschreibung
Zusammenfassung:	A boiler includes an enclosure having at least a supply for fuel and oxidizer and at least a supply for a SNCR reagent. The supply for the SNCR reagent includes at least a regulation valve for the SNCR reagent. The boiler includes at least a sensor for measuring information indicative of the NOx concentration over at least one given enclosure cross section. The boiler includes a controller connected to the at least a sensor and to the at least a regulation valve. The controller regulates the SNCR reagent supply according to the measured information indicative of the NOx concentration.
