The change of ammonia concentration distribution at the inlet of SCR reactor with injection ammonia concentration under the scheme I

Under scheme I, the impact of individual ammonia injection in regions A1, A2, A3, and A4 on the ammonia concentration distribution at the catalyst inlet was studied when the ammonia injection velocity was maintained at 6 m/s and the injection concentration was increased from 1% to 9%. In the figure, each coordinate interval corresponds to 1 m of the study object.
