| Abstract: | Directing against the problems of water-wall tube burst and leakage in seal-water tank for a 2100 t/h boiler in one thermal power plant, the cause analysis has been carried out through several means, such as macroscopic examination, chemical composition analysis, mechanical performance analysis, and metallurgical structure analysis etc.. It is considered that the tube burst belongs in stress pull-breakage, and corresponding preventive measures and recommendations having been put forward for the said failures. |
