Abstract
Fe- and Ni-base alloys including an alumina-forming austenitic alloy were exposed for 500 h under metal dusting environments with varying temperature, gas composition and total pressure. For one H-2-CO-CO2-H2O environment, the increase in temperature from 550 to 750 degrees C generally decreased metal dusting. When H2O was added to a H-2-CO-CO2 environment at 650 degrees C, the metal dusting attack was reduced. Even after 5000 h at a total pressure of 9.1 atm with 20%H2O, the higher alloyed specimens retained a thin protective oxide. For gas mixtures containing little or no H2O, the Fe-base alloys were less resistant to metal dusting than Ni-base alloys. (C) 2014 Elsevier Ltd. All rights reserved.
