Metallurgical failures in fossil fired boilers
Book
·
OSTI ID:6625584
Forty case histories of boiler shut downs resulting from metallurgical failures are presented. Reasons for the failures are traced, and the fundamentals of elementary metallurgy are explained to help non-metallurgists understand these practical examples. The full range of expected tube failures is covered, including microstructural changes, high temperature and creep ruptures, corrosion caused by poor steam side chemistry, fuel ash corrosion, and weld problems. Cases that relate steam-side conditions with fireside oxidation, corrosion and creep failures are provided. The effects of misuse or thermal abuse are also presented. Finally, there is a discussion of boiler design in terms of how to avoid these problems, minimize service failures, and improve maintenance.
