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).

主权项

1. A gas turbine silencer installed between an air intake port and a compressor of a gas turbine, the gas turbine silencer comprising:
a plurality of plate-shaped divided silencer panels aligned at predetermined intervals in a direction orthogonal to a flow direction of a fluid from the air intake port toward the compressor; the divided silencer panels wherein a surface thereof with a greatest plate area is arranged in orientation along a flow of the fluid, the divided silencer panels comprising an upstream silencer panel arranged on an upstream side in the flow direction of the fluid, and a downstream silencer panel arranged on an downstream side of the upstream silencer panel and linked with the upstream silencer panel; one silencer panel out of the upstream silencer panel and the downstream silencer panel being formed with an opening opened on a side facing the other silencer panel; the other silencer panel being formed with a fitting section fitting into the opening; and the upstream silencer panel and the downstream silencer panel being linked by the fitting section of the other silencer panel fitting into the opening of the one silencer panel.
