Prohibition of Boiler Feed Water Pump Failure in Power Plant

This paper deals with failure investigation of boiler feed pump’s shaft of a steam power plant. boiler feedwater pump is a specific type of pump used to pump, feedwater into a steam boiler and is one of most important part of steam power plants. feed pumps failure may cause failure of other parts of steam power station, therefore keep them safe, which is an important problem. there are 12 feed pumps in bandar abbas power plant. they are old and due to failure of feed pumps because of trying to avoid repetition problem, working condition of 3 dimensional pump’s shaft is modeled with abaqus software via finite element method analysis. causes of pump failure and stresses exerted on it are investigated and finally appropriate suggestions such as smooth starting and inverter are proposed.
