| Abstract: | Taking the steam generator of a 600WM supercritical once-through boiler as the object of study,based on the basic equation of the processes,this paper establishes a dynamic model of the one phase flow and the two phase flow using the substantial derivative method,and a nonlinear spatial mathematical model under subcritical and supercritical condition is gained.Using this model,dynamic characteristic of 600WM supercritical once through boiler under various typical working conditions is studied.The results pr... |
