“…These ferritic steels have been described deeply in previous works. [ 14–16 ] Finally, the AISI 304 is a stainless steel with a Cr content greater than 17 wt%. In addition, this steel also has 8 wt% of Ni, which increases its corrosion and creep resistance.…”

“…[ 17 ] However, under corrosive conditions, the protection may change due to fluxing of the protective scales. Therefore, Abang et al [ 16 ] investigated the same ferritic steels T24, T92, and VM12, and two austenitic steels (A800HT and 7RE10) with more than 20 wt% of Cr exposed to alkali sulfates in fly ash deposits. After 2000 h of exposure at 600°C, the authors found that metal wastage increased by decreasing the Cr content under oxy‐coal conditions.…”

“…The effect of oxygen concentration on the concentration of major and trace elements in ash was studied by Oboirien et al . Through XRD analysis of the collected fly ash, it was found that, under Oxy conditions, some minerals in the ash were carbonized and formed carbonate minerals such as CaCO 3 . Qu et al .…”

“…The effect of oxygen concentration on the concentration of major and trace elements in ash was studied by Oboirien et al 26 Through XRD analysis of the collected fly ash, it was found that, under Oxy conditions, some minerals in the ash were carbonized and formed carbonate minerals such as CaCO 3 . 27 Qu et al 28 studied the release characteristics of PM2.5 under Oxy and Air conditions on a test bed and showed that a high oxygen concentration contributed to the release of PM2.5, and elements such as S, Na, and K were enriched. Wall et al 29 found that, with the same combustion temperature and heat transfer conditions, the ash obtained from the Oxy and Air conditions had a similar composition and melting behavior, and the coal with higher calcium content had more sulfur in the ash.…”

“…The using of a laser beam leads to changes in the structural, physical, chemical, and mechanical properties in the particular areas of the processed objects [11]. Therefore, the proposed laser welding is a proper technique to joint dissimilar materials such as martensitic (0.13% C-11.4% Cr) to austenitic (X10CrNi18-10) stainless steels [12,13]. In laser welding, the weld material is a mixture of the two steels being joined.…”
