HIGH TEMPERATURE SEAL AND METHODS OF USE

摘要

A seal ( 1 ) includes a first component ( 7 ) and second component ( 9 ), the first component including a first material having a high thermal and oxidation and wear resistance, and the second component ( 9 ) including a second material that is different from the first material and has a high spring load maintenance. The seal ( 1 ) is applied to a combustion chamber for a gas turbine, where the first component ( 7 ) extends between the casing wall of the combustion chamber and adjacent liner segments ( 4 ). The spring load of the second component ( 9 ) provides a seal also in the case of vibrations in a combustion chamber. The lifetime of the seal ( 1 ) is increased due to the individual materials, which are optimally chosen for the functions of high thermal and wear resistance and spring load maintenance respectively. The seal is further applied to the sealing between adjacent stationary blade platforms in gas turbines.
