| Abstract: | There are many special requirements during the design of ultra supercritical steam turbine.Many technical problems need to be solved,including the prevention of solid particle erosion(SPE) of flow path and steam flow excited vibration of HP rotor,material selection of steam turbine,cooling structure of rotor and small LP steam inlet volumetric flow.These are crucial to the safe,stable and economical operation of the ultra supercritical steam turbine.In this paper,emphasis is placed on how to prevent SPE of flow path and steam flow excited vibration of HP rotor. |
