Device and method for preventing leakage of air between multiple turbine components

摘要

A turbine comprising a first turbine component being of a first material having a first coefficient of thermal expansion. A second turbine component being of a second material having a second coefficient of thermal expansion, said second turbine component adjacent said first turbine component. A space between said first and second turbine components. A seal assembly sealing said space, wherein at least a portion of said seal assembly has a coefficient of thermal expansion substantially similar to at least one of said first or second turbine components to thereby maintain a seal in said space during thermal expansion or contraction of said first and second turbine components.

1. A turbine, comprising:
a first turbine component being of a first material having a first coefficient of thermal expansion; a second turbine component being of a second material having a second coefficient of thermal expansion, said second turbine component adjacent said first turbine component; a space between said first and second turbine components; a seal assembly sealing said space, wherein at least a portion of said seal assembly has a coefficient of thermal expansion substantially similar to at least one of said first or second turbine components to thereby maintain a seal in said space during thermal expansion or contraction of said first and second turbine components; wherein said first turbine component is a liner of a combustor; and said second turbine component is a first stage nozzle; wherein said seal assembly further comprises a seal member and a seal carrier enveloping at least a portion of said seal member such that said seal member is isolated from contact with at least one of said liner or said nozzle; and wherein said seal carrier further comprises a first member between said liner and a first end of said seal member and a second member between said nozzle and a second end of said seal member.
