Identifying Hydrogen Damage In Furnace Waterwall

Furnace waterwall tube failures represent a leading cause of forced outages in power boilers. These failures occur as a result of a variety of causes, including under deposit corrosion, overheating, erosion, wastage, graphitization, and fatigue. Under deposit corrosion mechanisms such as hydrogen damage and caustic gauging are often the most difficult damage mechanisms to detect.
