All of these factors combined led to an accelerated deterioration of the header. deposits corrosion products hydrogen sulfide oxygen sulfur operational practices oil...

... is observed for the samples exposed when firing Fuel 1 (low Pb&Cl). On the contrary, a clear temperature dependence is observed in its corrosion behavior when exposed when firing Fuel 2 (high Pb&Cl). Surface analysis of the deposits shows in general an increased amount of chlorine in the deposit...

...Abstract The presence of sludge-like deposits and interstitial liquid may create susceptibility to underdeposit corrosion in high-level waste tanks. As the sludge deposits form occluded regions or crevices with the tank bottom, the chemistry of interstitial liquid could become sufficiently...

... inspection. There was no significant build-up of external surface deposits noted. Abstract Each boiler design presents its own challenges to ensure reliable operation, and some are more sensitive than others. A failure occurred in the finned, carbon steel tubing in the Waste Heat Boiler Coil at a large...

... sulfides (FeS) and iron oxides. Black Powder is known to cause serious problems to pipelines, such as flow inefficiency, product contamination, wear, plugging, and under deposit corrosion. Another major concern is the possible formation of elemental sulfur, which could be produced as a by-product...
