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.
