Abstract:
1. A brush seal carrier assembly adapted for insertion in a radially-oriented annular groove in a stationary turbine component comprising: a compliant brush seal component sandwiched between and engaged by an aft backing plate and a forward plate, said aft backing plate and said forward plate sized and shaped to fit into the radially-oriented annular groove; said compliant brush seal component, said aft backing plate and said forward plate being radially oriented and substantially parallel such that a radially inner portion of said compliant brush seal component projects radially beyond said aft backing plate; and at least one hard tooth seal element integrally formed with said forward plate so as to extend in generally parallel relation to said compliant brush seal component, wherein said hard tooth seal element extends radially beyond said aft backing plate but radially short of said compliant brush seal component; and wherein said at least one hard tooth seal element is axially spaced from said compliant brush seal component a distance at least three times a width dimension of said compliant brush seal component; and further wherein at least one of said forward plate and said backing plate is formed with a hook portion for engagement within a channel portion of the radially-oriented annular groove in the stationary turbine component.
