LSTM-SAFCN model based NOx emission prediction for biomass boilers
In view of the dynamic characteristics of the biomass boiler combustion process,this paper proposes a long short-term memory-self attention fully convolutional network(LSTM-SAFCN)to predict NOx emission.Firstly,a complete ensemble empirical mode decomposition with adaptive noise(CEEMDAN)is applied to preprocess the noise existing in input data.Secondly,the long short-term memory fully convolutional network(LSTM-FCN)is combined with self-attention method for feature extraction and prediction modeling,which takes both the local de-tails of series data and long-term prediction tendency into account.Finally,the effectiveness of the proposed algo-rithm is verified on a biomass cogeneration system.
