主要从固体粒子腐蚀 (SPE)及喷嘴高频激振两方面 ,研究某 30 0MW亚临界汽轮机调节级喷嘴出汽边断裂事故的原因 ,并提出改进的措施
In this paper, the causes of steam-side rupture at the regulating nozzle of a 30MW sub-critical steam turbine are studied from two aspects of solid particle erosion (SPE) and nozzle high-frequency excitation. The improvement measures
