Condenser is one of the main auxiliary equipments of thermal power sta tion. The structure and force of tube-sheet are very complex

as a matter of wha t the current researches for the thickness of tube-sheet are mostly based on emp iricism. By adopting finite element method to analyze the intensity of the conde nser

this paper properly simplifies the original model

which can serve as a ba sis for the optimization of tube-sheet structure of condenser and can enhance th e economical efficiency of manufacture.
