【Abstract】 The basic thermodynamic model of heat exchanger is presented in this paper.Based on it an approach to the heat exchanger tube fouling is developed.Fault can be diagnosed through continuously monitoring the changes of UA.Using the strong abilities of artificial neural networks(ANN) in self-learning and mode distingguish,the fouling of heat exchanger is identified through the Perception ANN model.更多还原
