- Abstract
This paper presents two case studies involving early-in-life failures in water-tube boilers, with an emphasis on the metallurgical analysis utilized in determining the root causes. The two failures presented here demonstrate different failure modes boilers can suffer, even after operating for just a fraction of their design lives. The first case presents a large rupture in a baffle header that occurred two years after plant startup. The failure exhibited the classic signs of hydrogen damage, likely caused by deficient water chemistry control. The second case presents a classic case of moderate temperature, long-term overheat in a boiler that had been operational for three years.
