Failure Analysis of Boiler Tubes at LPGCL (Khanote)
Journal Title: International Journal of Modern Research In Engineering & Management. - Year 2019, Vol 2, Issue 3
Abstract
Failure of boiler tubes in a thermal power plant is a very common phenomenon. So run the plant safely it is imperative for every plant owners to investigate the reason of failure and find out the remedies to prevent frequent plant shut downs. This paper, therefore, aims to provide the failure analysis report of boiler tubes at Lakhra Power Generation Company limited LPGCL (Khanote). The investigation is comprised on visual examination, fractography analysis, microstructural investigations and chemical analysis of the tube material. Optical microscope, Scanning electron microscope (SEM), X-Ray diffraction (XRD) and electron dispersion spectroscopy (EDS) techniques were used. Results indicated that the major cause of failure was localized short-term overheating of the tube due to improper material used for manufacturing of boiler tube. The fracture appearance is called fish mouth opening.
