摘要：

In order to establish a high precision NOx emission prediction model for coal-fired boilers, a deep learning-based NOx emission modeling algorithm considering the time-delay characteristics was proposed. First, the importance of characteristic variables was analyzed by combining mechanism analysis and lasso algorithm, and the variables most related to NOx emissions were selected. Furthermore, the time-delay correlation between the selected variables and NOx information and time domain information, and construct the modeling database. Finally, the deep neural network structure and parameters were designed to build a NOx emission prediction model. The experimental results based on the actual operation data of the thermal power plant show that the prediction error of the proposed algorithm is less than 2% under various working conditions, which can meet the requirements of actual production on the prediction accuracy. © 2020 Chin.
