Abstract: | Based on the method of data processing and analysis,a large amount of actual data stored in the DCS of power plant are fully utilized.With relevant parameters of SCR system as input and NOx concentration at SCR outlet as output,BP neural network is used to construct the prediction model of SCR denitrification system.The model fully considers the relationship between denitrification efficiency and other variables.The experimental results show that the prediction results of the model are reliable,providing a model basis for the optimization of denitrification system in the next step and the realization of energy saving and emission reduction. |
