Research On Dynamic Mathematical Model Of The Heat Recoup System For Large Thermal Power Unit

The three-section feedwater heatCrs, Which are widely used in heatrecouP system of the large thermal power unt, are taken as the obect tobe stUdied in this paPer. The dynandc mathematical model of the heaterand the economy analysis model of the heater recouP system are built byinveshgating deePly on the strUctUre, the OPerating characteristic and theheat transfer theories of the heaters and the heat recouP system. The heaterconstrUchon parameters and the physical PrOperty of the wObong mediumare fully considered in the model. The difference betWeen the staticcalcuation formula and the dyndric model is also considered. Thestatic accuracy and dynamic performance of the mathematic model of theheater are verified by detailed simulaton tests and by practicalengineering aPPlication. The economy of the heat recouP system underdifferen wOrk cOndihon is analyzed with the system economy analysismodel.Zhao Wensheng (Thermal Power Engineering )Directed by Pro f Wang Bingshu...
