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
High-temperature oxidation of alloysSpringer Science and Business Media LLC - Tập 2 - Trang 11-57 - 1970
Graham C. Wood
Some recent developments in the understanding of the oxidation of alloys at elevated temperatures are reviewed, with special reference to binary and ternary alloys upon which many commercial materials are based. Following an initial classification of alloy systems, certain basic principles and their limitations are considered, including factors determining whether an alloy displays surface scalin...... hiện toàn bộ
Influence of Water Vapor on the Cyclic-Oxidation Behavior of a Low-Pressure Plasma-Sprayed NiCrAlY CoatingSpringer Science and Business Media LLC - Tập 62 - Trang 195-206 - 2004
Chungen Zhou, Huibin Xu, Shengkai Gong
The oxidation of a low-pressure plasma-sprayed (LPPS) NiCrAlY coating on a nickel-base superalloy was studied at 1050 °C in flows of O2, and mixture of O2 and 5% H2O under atmospheric pressure. Water vapor has an obvious effect on the cyclic oxidation of the NiCrAlY coating. There is more decrease in weight gain when exposure to O2 is replaced by exposure to O2 + 5% H2O. The oxide formed on the LP...... hiện toàn bộ
Evolution of grain structure in nickel oxide scalesSpringer Science and Business Media LLC - Tập 28 - Trang 353-389 - 1987
H. V. Atkinson
In systems such as the oxidation of nickel, in which grain-boundary diffusion in the oxide can control the rate of oxidation, understanding of the factors governing the grain structure is of importance. High-purity mechanically polished polycrystalline nickel was oxidized at 700°C, 800°C, and 1000°C for times up to 20 hr in 1 atm O2. The scale microstructures were examined by parallel and transver...... hiện toàn bộ
