Boiler Tubes Failures: A Compendium of Case Studies
- 311 Downloads
Boiler tubes are a vital component in the steam/power co-generation plants. Depending on materials, fuel used, and operation practices, different failures could occur. Most of these failures induce shut-down for corrective maintenance. During the last 30 years, steam/power co-generation plants that serve desalination were subject to classical and particular boiler tubes failures. This paper is dedicated for the presentation of some particular failures of boiler tubes that have been studied previously. The particularity originates from the mechanisms combination, the unsuitability of certain surface treatment, etc. Different cases are discussed and some lessons are outlined with regard to operation and maintenance practices that should be respected for boiler tubes integrity.
