Steam seal is an important part in steam turbine, the leakage performance of seal has a significant impact on turbine efficiency. Research of seal is greatly emphasized with the development of design and manufacture technology, more professionals committed to the research and develop of new-type seal. Researchers from Shanghai power equipment research institute have conducted leakage performance test of different kinds of steam seal on the seal test bed. This paper introduce result of four kinds of seal, including labyrinth seal, honeycomb seal, touched seal and brush seal. The test analyzed blocked performance of different kinds of seals and concluded the suited scope of different seals.
