In order to characterize the complicated corrosive environment around superheater tubes in advanced waste-to-power (WTP) boilers, thermodynamic simulation was conducted using the thermodynamic equilibrium calculation software MALT for Windows. The macroscale of thermodynamically stable compounds at an equilibrium state can be obtained using this software, which is applicable for predicting the mac...... hiện toàn bộ
Fireside Corrosion of Ni Base Self-Fluxing Alloy Coatings in WtE Plant: Effect of Flue-Gas and Metal TemperatureSpringer Science and Business Media LLC - Tập 87 - Trang 741-756 - 2017

Increase in the efficiency of energy recovery facilities is one of the challenges facing waste-to-energy (WtE) operators in the EU. To achieve this target, one option is optimization of the water/steam cycle to increase electrical efficiency. Nevertheless, increase in steam temperature in heat exchanger tubes results in increased fireside corrosion risks, particularly in superheater tubes, where s...... hiện toàn bộ
The oxidation behavior of an aligned Co-TaC eutectic alloySpringer Science and Business Media LLC - Tập 9 - Trang 225-257 - 1975
J. G. Smeggil
The oxidation behavior of the directionally aligned eutectic alloy, TaC-Co50B, has been examined between 600 and 1155°C. Parabolic oxidation behavior, isotropic in nature, is found to 800°C. Above 800°C, the oxidation behavior is no longer either parabolic or isotropic. The interaction between the Co matrix alloy and the TaC fibers adjacent to the oxidizing interface is reported as a function of ...... hiện toàn bộ
Kinetics of oxidation of ferrous alloys by super-heated steamSpringer Science and Business Media LLC - Tập 28 - Trang 237-258 - 1987
Nicholas J. Cory, Thelma M. Herrington
The kinetics of the oxidation of ferrous alloys in steam (10–60 kPa) at 450–550°C have been studied by measuring both the rate of hydrogen emission and the amount of metal oxidized. Excellent agreement has been found between the amount of metal oxidized calculated from both the total mass of hydrogen produced in the reaction and the thickness of the oxide layer formed; rate constants calculated f...... hiện toàn bộ
The Sulfidation of Inconel 738 in H2/H2S/Ar Gas Mixture at 500–900°CSpringer Science and Business Media LLC - Tập 61 - Trang 507-527 - 2004
W. Kai, Y. T. Lin, C. C. Yu, P. C. Chen, C.-H. Wu
The sulfidation behavior of the cast nickel-base superalloy Inconel 738 (IN-738) was studied over the temperature range 500–900°C in three various ratios of H2/H2S/Ar atmospheres having sulfur partial pressures in the range 10−4–102 Pa. The sulfidation kinetics followed the parabolic rate law in all cases, and the sulfidation rates increased with increasing temperature and sulfur partial pressure....... hiện toàn bộ
Water Vapour Effects on Fe–Cr Alloy OxidationSpringer Science and Business Media LLC - Tập 73 - Trang 337-352 - 2009

Isothermal oxidation at 700 °C of binary Fe–Cr alloys containing 9, 17 and 25 wt% chromium was measured using continuous thermogravimetric analysis. All alloys developed thin, protective chromia scales in Ar–20O2 (vol%). Chromia scale growth on the 17 and 25 Cr alloys was faster in Ar–20O2–5H2O and Ar–5O2–20H2O. In these gases, the Fe–9Cr failed to form a chromia scale and suffered rapid breakaway...... hiện toàn bộ
