Abstract

The SNCR-Method (Selective Non Catalytic Reaction) uses injection of ammonia to reduce nitrogen oxides present in stack gas produced by combustion facilities (e.g. power plants, waste incineration plants): 6N02+8NH3 —<7N2+12H20 4N0+02+4NH3—*4N2+ 6H20. In order to achieve an optimum injection of ammonia the concentration must be determined immediately after the combustion process (Fig. 1).
