SILENCING TECHNIQUES FOR GAS TURBINE DRIVEN COMPRESSOR SETS FOR PIPE-LINE INSTALLATIONS.

The article discusses such techniques for an industrial gas turbine compressor set housed in an individual weatherproof acoustic enclosure. In the U. K. the majority of gas turbines used for this application have been of the aero-derived type, but the silencing and mechanical design problems are virtually identical to that of the industrial type of engine. A further variable is a site where, for reasons of economics and maintenance, multiple units are housed in a single building, normally constructed of concrete or a similar material. Among the points covered are noise from the gas turbine intake, exhaust and casing, from the driven unit, accessory package, acoustic enclosure ventilation, pipe work, oil cooler and filter.
