Spray denitration system

During combustion in the boiler, nitrogen oxides (NOx) and other flue gases are generated, and ammonia water (NH3) is sprayed into the flue gas through a nozzle. Both Non Catalytic Denitrification (SNCR) and Catalytic Denitrification (SCR) methods use a two fluid nozzle with compressed air to reduce the average particle size and achieve effective chemical reactions.
