Stability Analysis of OTSG Based on Augmented Vector Bilinear Model

In order to achieve the more precise system characteristics,this paper builds the model of the heat exchange process of OTSG based on the augmented vector bilinear system according to the lumped Lyapunov theory in the light of the steadily parameters in some rating condition.The result shows that that system is vulnerable with the pressure loss coefficient dropping down when the power is fixed,and with the increasing of the power,the system is more steady because of the length of the preheated region getting longer
