Abstract : Economizer and superheater boiler tube alloys of 1018 carbon steel, 2-1/4Cr 1Mo steel, and 316, 321, and 347 stainless steels were exposed to burner rig tests at 310 F and 975 F (155 C and 524 C), which respectively are typical economizer and superheater temperatures. The tests were made using MIL-F-16884H Navy distillate fuel with 0.0 and 0.3 ppm vanadium content. This was done to reveal problems that might result from adding vanadium to the fuel. The corrosion of the alloys at 975 F (155 C) did not significantly increase in the 0.3 ppm vanadium test. However, it did appreciably increase at 310 F (155 C). This increase was related to sulfuric acid condensation. The dewpoint of the sulfuric acid may have been raised by the presence of vanadium. The 316 stainless had the best resistance to this corrosion. Boiler tubes, Stainless steel, Burner rig, High temperature corrosion. (JES)
