“…Such Cl-induced corrosion will be dependent on many factors. One study 118 showed that the O/Cl ratio had a great impact on the active oxidation and lower O 2 content resulted in higher metal loss. 118 The temperature also plays a crucial role.…”

“…One study 118 showed that the O/Cl ratio had a great impact on the active oxidation and lower O 2 content resulted in higher metal loss. 118 The temperature also plays a crucial role. A modeling calculation revealed that it was the flue gas temperature instead of the tube wall temperature that affected the deposition and subsequent corrosion of vapor-condensed Cl from flue gas.…”

With the desire for a clean living environment and the increasing demands for cost competitive energy supply, advanced fuel combustion technologies have been proposed and are being developed. The deployment of these technologies has been hindered by unanticipated corrosion damage within core components (such as boilers and flue gas components) at pilotscale demonstration plants. To deal with such materials technology challenges, studies have been carried out, but there is still substantial R&D required to meet the emerging industrial demands. A comprehensive review of open database information regarding the corrosion of flue gas systems in existing combustion plants was therefore conducted in this review. It is anticipated that this information will provide a basis for addressing knowledge gaps in materials technologies and advancing the mechanistic understanding of how alloys corrode in flue gas operating environments. Corrosion modes, the effects of aggressive agents (including CO 2 , HCl, SO x , and NO x ) in flue gas mixtures, and the performance of candidate metallic materials in typical combustion systems are systemically reviewed and discussed. From corrosion and economic points of view, F/M steels (P91 and P92), austenitic stainless steels (SS317, 254SMO, and 654SMO etc.), and duplex steels (2205 and 2507) are likely to be major candidates for the construction of future flue gas systems in the fossil fuel powered industries. Ni-based alloys, particularly Alloy C-276 and Alloy C-22, are more applicable for flue gas components in biomass and waste-to-energy energy combustion systems.

“…Consequently, melts and substances with hygroscopic and deliquescent properties are formed and a high corrosion potential arises. All in all, the situation will be similar as described for other high-contamination, high-temperature facilities, and technologies [11][12][13][14][15].…”

The present work deals with the corrosion of mild steel (1.0037) used as the outer construction material of the preheater of a modern industrial cement production facility. The facility uses secondary fuels, which introduce considerable amounts of corrosive species. The situation at the examination sites in the preheater zone is tracked over a period of two years including operation and shut-down periods. The investigation is focused on (i) the acquisition of the underlying physicochemical conditions, such as moisture, temperature, and contamination data at the examination site of the preheater, (ii) the multianalytical identification of the formed corrosion products using scanning electron microscopy combined with energy-dispersive X-ray analysis, infrared spectrometry, Raman spectrometry, X-ray diffractometry, and Möβbauer spectrometry, and (iii) voltammetric and EIS laboratory investigations using model solutions. It was evidenced that corrosion takes place at a temperature level of about 100°C in the presence of moisture and oxygen as well as chloride ion as a consequence of the usage of secondary fuels. Typical hot-gas corrosion could be excluded under the current conditions. Appearance, structure, and nature of the corrosion products were found to be not mainly dependent on the varied length of exposure, but on the conditions of the hosting preheater intake. In addition to different FeOOH phases and hematite, magnetite was found, dependent on the oxygen concentration in the process gas. The decisive role of oxygen as key factor for the corrosion rate was electrochemically confirmed.

Corrosion of 15Mo3 carbon steel superheater tubes in waste incineration plants: A comparison between a field‐returned tube and laboratory tests

In this study, a field‐returned superheater tube of carbon steel 16Mo3 (1.5415) was analyzed in detail. In addition to cross‐section analysis, different scales were investigated layer by layer using microscopic, diffraction, and spectroscopic techniques. The corrosion products can be divided into three layers: The layer adjacent to the metallic tube surface was an iron‐ and chlorine‐rich scale, followed by an FeS layer present at the gas flow side, and the outermost layer was an iron oxide scale consisting of Fe3O4 and α‐Fe2O3. The different mechanisms responsible for the structure of such scale formation and the different corrosion products formed at the tube are discussed. Furthermore, the root cause for the disability to form a protective scale under such conditions was identified by comparison with results from laboratory tests.
