Wet Compression Features V94.2 /V84.2 Product Line GT Design
The Siemens Wet Compression System ensures
Optimised positioning of spray rack and droplet distribution in the inlet duct (3D-CFD, Spider nozzles with more than 1000 spray points) to achieve lowest possible erosion wear on compressor blading
Core engine integrity by considering - Blade clearance and casing distortion - Surge line limits of compressor with Wet Compression - Cooling Air management (hot gas penetration turbine, water in bleeds) - Axial thrust of the gas turbine - Drainage for water
