After 23 years of operation, the fire tube of a 2000 kg steam/h boiler broke down in a water-filling operation. Because of the intense vaporization processes, the boiler body blew up at about 250 m. The study of metallographic features, of mechanical properties in various areas of the fire tube poin...
