This paper chronicles the approximate 10 year history of the performance of alloy 825 superheater tubes in a municipal waste incinerator. In addition, results of test spools and installed tubulars in other waste incinerators are reported. Alloy 825 superheater tubes have performed satisfactorily at Saugus, MA since 1977 with only 15 out of a total of 330 tubes having been plugged. Low operating skin temperatures, i.e. 800°F (427°C) and baffle design changes were important to increased life.
