| Abstract: | This paper introduces the practical investigation of the water fouling influence on condensers of steam turbines and the economic loss caused by the fouling.It is stated that the continuous self-clean and heat transfer enhancement principles with twisted strips.By experiments,it is proved that the clean ability can meet the condenser requirements well.The enhancement ranges from 9% to 15%.After quite long continuous operation in the experiments,the condensers don't show any sign of wear and tear.After calculation and analyses,it is showed that using the technology can increase notably the vacuum,output and efficiency of generating units. |
