Identification of black-box models and simulation for furnace of steam boiler

In this paper, four system identification methods are presented for modeling afurnaceof boiler in order to characterize the essential dynamic behavior of the furnace. The structures of the system identificationmethod consists of ARX ,AMX,OE and BJ. The measured data from a complete set of field experiments is the basis for training the models. Comparison between the responses of the proposed models with the responses of the plants validates the accuracy and performance of the modeling approach. A similar comparison between the responses of these models with the models obtained based on physical relations of the plant shows the effectiveness and feasibility of the developed model in terms of more accurate and less deviation between the responses ofthe models and the corresponding system
