| Abstract: | The three-section feedwater heaters, which are widely used in the large thermal power unit, are taken as the object to be invested . The dynamic mathematical model of the heater is built by investigating deeply on the structure, the operating characteristic and the heat transfer theories of the heaters . The heater construction parameters and the physical property of the working medium are fully considered in the model. The difference between the static calculation formula and the dynamic model is also considered. The static accuracy and dynamic performance of the mathematic model of the heater are verified by detailed simulation tests and by practical engineering application. |
