| Abstract: |
| Considering the present modeling and energy-using analysis of dryer section are not able to effectively integrate the material, energy and exergy flows analysis, the complex and multi-material heat and mass transfer processes of the multi-cylinder dryer section were divided into a number of relatively independent functional units and established the corresponding unit models by using the object-oriented method, the establishment of the unit model of the web was emphasicly introduced. All of the models possessed the analysis function of energy and exergy, and the analysis could be integrated with the traditional material flow analysis. The module flow diagram of dryer section was constructed based on the sequential modular approach. Case study showed that the developed models were reasonable and the simulation results were nearly consistent with the actual measuring results. The amount of fresh steam could be saved and specific consumption of stream reduced by means of adjusting the inlet flow or pressure of fresh steam of different dryer sections. |
