the liquid droplet injection device 32 a the intake manifold 26 which guides the intake air into the compressor as smoothly as possible is connected to the entrance of the compressor 1 2 which in this case is a compressor without inter cooling alternative locations for the liquid droplet injection device are e g at the compressor bellmouth as close to the compressor entrance as possible 32 b or behind the silencer 32 c both elements 29 and 32 a b c preferably inject demineralized water in order to avoid depositions in the gas turbine unit typically 1 0 to 3 0 mass of water are added to the stream of intake air and a water pressure of gt 100 bar is used to visualize in more detail the conditions in the intake region of a gas turbine unit fig3 shows an axial cut through a gas turbine unit and in particular through its intake manifold 26 it can be seen that the liquid droplet injection device 32 a is arranged substantially perpendicular to the flow of intake air 10 at the interface between the intake duct 27 and the intake manifold 26 preferably the liquid droplet injection device 32 a is positioned on the intake.
