Abstract:
This paper presents creep analysis to estimate the remaining life of tubes used in water tube boiler. Three dimensional finite element (FE) models were developed with computer software namely ANSYS Workbench 10.0 to analyze the tube temperature and stress distribution. The FE results showed that the temperature and stress increase as the oxide scale thickness increases. Formulating the creep behavior in terms of well established creep laws, the remaining life of the tube was estimated.
