Liner assembly for gas turbine combustor
First Claim
1. A liner assembly for a combustor used in connection with a gas turbine, said liner assembly comprising:
- an outer structural shell;
a separate throat insert flexibly coupled to and situated in said outer shell;
said throat insert including a reduced throat section effective to divide said outer shell into an upstream chamber and a downstream chamber;
a plurality of upstream fingers defined by a plurality of slots in an upstream end of said throat insert;
means for connecting each of said upstream fingers to said outer shell; and
a plurality of downstream fingers on a downstream end of said throat insert, said downstream fingers including means for coupling said downstream end to said outer shell.

Abstract
A liner assembly for a combustor used in connection with a gas turbine is disclosed. The liner assembly comprises a double-wall structure including an outer structural shell and a separate throat insert coupled to and situated in the shell. The throat insert has a reduced throat section which divides the outer shell into upstream and downstream chambers. The upstream end of the throat insert is flexibly coupled in a stationary position to the outer shell by integral fingers and the downstream end is flexibly coupled to the outer shell, preferably by an air seal incorporating a plurality of flexible fingers located at the downstream end of the throat insert.
