Findings of a continuing in situ flue gas desulfurization (FGD) scrubber exposure test program used to assess the performance of specific titanium alloys in corrosive inlet quench and outlet duct areas of FGD systems are reported and discussed. Spool rack exposures of four to nine months in power plant FGD and particulate scrubbers provided corrosion data for titanium alloys relative to the corrosion resistant alloys commonly considered for this service. Overall, Titanium Grade 2 and Grade 12 equalled or exceeded the corrosion resistance of the stainless steel and nickel base alloys tested. Titanium Grade 7 exhibited the best corrosion resistance in the wet/dry zone of the inlet quench of a closed-loop FGD scrubber. This performance is correlated with laboratory studies in the literature, and a mechanism is proposed to explain titanium's corrosion resistance.
