About 125 small-scale burner tests were run to investigate high-temperature corrosion of alloy steel by ash from residual fuel oils. In most of these tests a specimen of AISI-310 stainless steel (25-20 Cr-Ni alloy) was exposed for 100 hours at 1450°F. to the combustion gases of No, 6 or Burner Fuel Oil-Navy Special containing 150–200 ppm vanadium, without or with experimental additives. The small-scale burners and a full-scale ten-inch combustor (from a Westinghouse gas turbine) operated at substantially atmospheric pressure showed very good agreement with respect to corrosion and deposits formed in 27 comparative tests.
