Abstract |
|
There are failures in the industrial power plant mainly due to the boiler tubes and pipes of different zones. Failure may occur due to various reasons. These include the failures due to creep, corrosion, erosion, overheating, fatigue, welding defects, etc. This paper presents the results of investigation, which was carried out to determine the failure causes. The numerical simulation is carried out in ANSYS mechanical software. The results indicates that the evaporator tubes and header pipe was subjected to high temperature and pressure. There were cracks formation in the material at the joints of tubes and header due to which there was the leakage and failure. It is also determined that the proper expansion of material was not given due to the same, there were thermal stresses generated, and failure occurs. The failure reason was known from the numerical analysis and the same was incorporated in future. |
