Abstract: The aim of this study is to analyze the causes of tube failure of the high pressure feed water heaters in thermal power plants and to find out the defective tubes in high pressure feed water heaters using simple and economical method. A feed water warmer is utilized to preheat the kettle feed water in warm power plant. The majority of the feed water radiator utilized in warm power plant is shell and cylinder type. In this kind of feed water warmer, water streaming inside the cylinder and steam consolidating in outside of the cylinder i.e., shell side. The wellspring of warmth utilized in high weight feed water warmer is steam seep from the turbine. The high weight feed water radiators are utilized to improve the thermodynamic effectiveness of the cycle and furthermore diminish the coal utilization of the warm power plant. Test of the disappointment cylinder were taken to investigate the reasons for cylinder disappointment in high weight feed water radiator by visual review, utilizing tube thickness estimation examination, Examining Mechanical properties and substance structure of the cylinder material and strategies for finding the cylinder disappointment ahead of time to counteract the breakdown of high weight feed water warmers. In light of the above investigations, it is seen that the high weight feed water warmer cylinders disappointment happened because of cylinder external distance across disintegration.
