.... This accelerated sulfidation attack due to salt deposits is frequently referred to as “hot corrosion” in gas turbines ( Chapter 9 ), “coal ash corrosion” in coal-fired boilers ( Chapter 10 ), and “oil ash corrosion” in oil-fired boilers ( Chapter 11 ). They are discussed in these chapters. Oxidizing...
