Abstract

Arrangement at a gas turbine installation for the generating of electricity, where inlet air filter housing, bleed air outlet and inlet for the vent air to the turbine housing are integrated into two units, an upper filter housing and a lower intermediate housing connected to the turbine housing. The lower intermediate housing includes a silencer for the inlet air that at the same time connects the filter housing with the turbine inlet. The compressor bleed air system is divided into two parts, one in the intermediate housing and one extending through the filter housing. The vent air for the turbine housing is drawn in through an end wall of the filter housing and down into the turbine housing through separate spaces surrounding the compressor bleed ducting in the filter and intermediate housings.
