Abstract:A survey on the research of the steam excitation of the superior ultra-critical steam turbine is given in this paper. The mechanism of the steam excitation is analyzed and summarized. The developing status of the research of the steam excitation is also introduced. Some types of effective seal structures of foreign turbine manufacturer are presented. The ways to preventing steam excitation are also summarized. Finally, the future research orientation of steam excitation is also discussed.
Keywords:ultra-supercritical  steam turbine  steam excitation
