Abstract

The leakage reasons for a boiler enclosure wall superheater were discussed based on experimental results of macro fracture observation, chemical composition analysis, metallurgical microstructure examination, SEM and EDS analysis. It was presumed that weld flaw firstly formed due to large weld process parameters, then propagated under long period fatigue stress and developed to penetrated crack, leading to final leakage. It was suggested that boiler supervision and four-tube inspection should be enhanced.
