This paper deals with a failure investigation of boiler feed pump’s shaft of a steam power plant. Boiler feed water pump is a specific type of pump used to pump, feed water into a steam boiler and is one of most important part of steam power plants. Feed pumps failure may cause failure of another part of steam power station, therefore keep them safe is an important problem. There are 12 feed pumps in Bandar Abbas power plant. They are old and because of failure of one of them and for trying to avoid repetition of this problem, work condition of 3 dimensional pump’s shaft is modeled with Abaqus software that uses finite element method for analysis. Causes of failure of pump and stresses forced on it are investigated and finally some suggestions likes use of soft starting and inverter are presented.
