Metallurgical Failure Analysis: มิถุนายน 2010
Fig.1 Boiler tube for failure analysis. In this case study, the failed component was the evaporator tube, which had been in service for nearly 4 years. The tube was the component of the evaporator outlet of the low-pressure steam in the heat recovery steam generator (HSRG). The tube was used for feeding water to the continuous process for boiler.
