摘要
Abstract
The bursting and leakage reason of final superheater T91 steel tubes of a ultra super critical boiler was analyzed through chemical compositions analysis, microstructure analysis and mechanical properties test. The results show that the failure of the final superheater tubes was due to overheat which deteriorated the microstructure and mechanical properties of the tubes material. It was believable that the overheat of the bursting tubes was caused by blockage, according to the analysis results on the spot.关键词
