Summary: The overall goal of this project is to find out if Selective Non-Catalytic Reduction (SNCR) technologies can be used in grate-kiln plants for NO\(_{\text x}\) reduction. The technique has, to the best knowledge of the authors, never been used in this context before, despite that it is commonly used in cement and waste incineration plants. A model for spray injection into the grate was included in the model enabling a study of the overall mixing between the injected reagent droplets and the NO\(_{\text x}\) polluted air. The simulations indicate that the SNCR-technique works with urea, but not with ammonia.
