Inlets, Exhausts, and Noise Suppression
The inlet to a gas turbine is designed to promote optimum air swallowing capability. Land- and marine-based engines frequently are equipped with inlet air filtration systems to protect the gas turbine against ingestion of contaminants potentially including, but not limited to, salt sea spray, insects, sand, and oil stack fumes. These contaminants could coat themselves on the airfoils in the compressor or further downstream and cause erosive or corrosive damage to gas turbine components. Most gas turbines, therefore, are fitted with wash systems. This chapter also covers gas turbine exhausts, methods of noise compression, etc.
