Description

In this document, the detailed description of the tube failure mechanisms mostly encountered in Heat Recovery Steam Generators (HRSGs) are given in alphabetical order under a certain format which standardizes the headlines of  the failure related topic. After the detailed description of each failure mechanism, sample failure pattern pictures being selected from different sources carefully and in color have been provided on the next page(s) for better identification of tube failure mechanisms.

Additionally, the major category of each corrosion type and its relation to other corrosion types have been clearly identified for easy cross-reference and understanding of the corrosion mechanisms. It is intended that this document is used for the self consultation of the applicant by comparing his own failure pictures with the ones therein to find the root cause of the failure.
