SEALING ARRANGEMENT FOR GAS TURBINE TRANSITION PIECES

摘要

A sealing arrangement for sealing between adjacent first and second exit frames each associated with a transition piece of a turbine. The arrangement includes a transition side seal having bristles that extend from a rail wherein the rail is bendable in a plurality of directions to accommodate bowing of an associated exit frame. The first exit frame includes a rail slot for receiving the rail. The second exit frame includes a bristle slot for receiving the bristles to form a seal between the first and second exit frames, wherein the bristle slot includes a bottom section. The bristles are separated from the bottom section by a bristle gap that is sized to accommodate movement of at least one transition piece to maintain a seal between the first and second exit frames or avoid damage to the bristles.
