Experience in combustion and waste incineration flue gas applications shows that the
corrosivity can vary widely depending on the range of fuel composition and location in the
flue gas cleaning plant. This paper describes different stainless steels that are used in flue
gas cleaning systems but also the behavior of the alloys in artificial scrubber environments
and results from field tests. An overall table showing the limits of different grades with
respect to chlorides, fluorides and temperature in simulated scrubber environments is
presented. Service experience confirming data from the different test is also included.
