| Abstract | ||
| ABSTRACT The low pressure steam Turbine blades are suffering especially the longest parts a bad history of failure. The breakage reasons are unknown due to its complexity. The aim of this work concentrated for the analysis of stresses at the last stage blades in Baji thermal power station. No records have been recorded of breakage incident at any other stages. The aim of the designer is to find way of reducing stresses due to centrifugal force.(ANSYS 12.1) is used for obtaining various stresses in case. Theblades without lacing rod, the blades with lacing rod. It was concluded throughout using (ANSYS) Techniques, analysis increasing stresses at the leading and trailing edge of blade root and a stress concentration at the upper mid of the blade. This indicates why a failure at the lacing rod and aerofoil occurred in this station | ||
