Summary 1. Laboratory test-stand studies have been made on the high-temperature corrosion of various alloys when burning fuels with sulfur contents from 0.3 to 2.4% and vanadium contents up to 0.0001% 2. It has been shown that, for the nickel-base alloys ÉI-598 and ÉI-607 and for the high-chrome steel ÉI-417, increasing the sulfur content of the fuel gives only a slight change in the amount of corrosion, all weight losses falling within the range 0.026–0.066 g/m2 · h. For the medium-sulfur diesel fuel, the metal weight losses were 0.038–0.073 g/m2 · h. 3. Using a fuel with 0.007% ash and 2.4% sulfur, increasing the gas temperature gave an increase in the amount of deposits on the blades from 0.001 to 0.002–0.004 g/cm2; when using the low-sulfur gas turbine fuels or the medium-sulfur diesel fuel, the amounts of deposits formed in 850°C tests were essentially equal (0.0006 to 0.0026 g/cm2). 4. Wide-range fuels with end points around 480°C produced from distillates of secondary origin from processing of medium-sulfur and low-sulfur feedstocks (excepting distillates from cokestill units) can be recommended for use in gas turbine units in various types of service.
