GAS TURBINE SILENCER, AND GAS TURBINE PROVIDED WITH SAME

摘要

Provided are a gas turbine silencer for avoiding the formation of gaps between an upstream silencer panel and a downstream silencer panel and suppressing the occurrence of secondary noise, and a gas turbine provided with this silencer. A silencer panel (41) has a structure that can be divided into an upstream silencer panel (51) and a downstream silencer panel (52) in an airflow direction, a stepped part (71) shorter in length along the alignment direction of the silencer panel (41) is formed in an opening-side portion of the downstream silencer panel (52), and the upstream silencer panel (51) and downstream silencer panel (52) are linked by the stepped part (71) fitting into substantially the entire opening (64) in the upstream silencer panel (51).
