“The pressure changes through the turbine blades would otherwise cause droplets of liquid to form that would chew up the blades.”
Rain?
Besides, the hot section turbine downstream of the combustion chamber (i.e., where this fuel is introduced) is running around 700 degrees Celsius. Not a lot of water droplets there.
There is a compressor section in the air inlet prior to the ignition chamber.
I’ve worked the installation of a quite a few turbine engines for Natural Gas compressors. The fuel gas specifications is VERY clear of how clean and dry it has to be to meet the warranty.
