Boiler tube failures (BTF`s) due to fly ash erosion are one of the leading single causes of availability loss in fossil boilers. The damage, which can be very localized, has led to expensive and lengthy forced outages. As part of an overall BTF reduction program, EPRI has documented the available solutions being applied for fly ash erosion.
