Minimizing the life cycle costs attributed to boiler tubine in fossil-fueled plants

摘要

During the past quarter century, much has been learned about tube degradation, the factors which lead to and influence the rate of damage, anc measures to mitigate or eliminate the damage in boiler tubing. This paper will describe some of the knwoledge which has been compiled regarding two of the most significant degradation modes--corrosion-fatigue of waterwall tubes and high temperature creep of superheater and reheater tubes.
