Flow accelerated corrosion has recently attracted attention in association with heat recovery steam generators. Apparently, the phenomenon is more widespmad than is realized and has been misdiagnosed as simple erosion. This paper addresses the principal enviromnental conditions that have been linked to flow accelerated corrosion and it
illustrates the phenomenon with case histories. Keywords: flow accelerated corrosion, heat recovery steam generators, electric power, utilities, wall thinning
