Abstract
A method for operating a gas turbine installation (1) includes sucking in a gaseous medium (2) by the compressor (3) and compressed in the compressor space, a liquid medium (10) being injected into the gaseous medium (2), so that a two-phase flow comprising a gaseous phase and a liquid phase is formed at least in a subregion of the compressor (3). The gaseous medium (2) is then burnt with fuel (5) in a combustion chamber (6) to form hot gases (7), and the hot gases (7) are expanded in a turbine (8), the hot components of the gas turbine installation (1) being cooled by cooling air (14) of a cooling air system. A measurement is carried out to determine whether a liquid phase is present in a region of the compressor (3) and/or of the cooling air system.
