Droplet Erosion

Gas turbines are generally considered the most cost effective and relatively environment-friendly large scale power generation technology, but their capacity as well as their thermal efficiency degrades under high ambient temperature conditions. Fogging Systems provide the most cost effective technique to recover this lost gas turbine capacity through adiabatic cooling of the gas turbine inlet air by the spraying of atomized water in the axial compressors. Nevertheless the water injection can cause droplet erosion phenomena on the first stages of blades of the compressor. That degradation can be avoided by applying an erosion/corrosion-resistant coating like our FlameSeal 834 System.
