Gas Turbine Air Filter Overview Introduction Proper air filtration is critical to the overall performance and reliability of gas turbines. The latest evolution in the filtration industry is the use of nanotechnology in this field. With this technique, the surface of large cellulosic or synthetic textiles (usually 10 to 30 micrometers in diameter) is covered with a layer of ultra-fine textiles (typically 50 to 400 nanometers in diameter). There are two different methods for separating particles in the filter paper structure. In-depth filtration, in which particles are separated in different layers of paper according to their size; and surface filtration, in which all particles are separated on the surface of paper. In Behran Co. before pleating process, the filter paper is covered with a layer of Polyamide textiles with diameter of less than 100 nanometer by using electrospinning process. Application The main application of this technology is in in air filtration of gas turbines with reverse pulse cleaning system Advantage of Using Nanotechnology Electrospinning is used to improve the performance and efficiency of the filter. This technology while increases the efficiency of dust absorption, avoid high pressure drop. Fibers produced by electrospinning have a diameter of less than 100 nm and cover the surface of the filter paper uniformly. The filtration efficiency was evaluated in accordance with EN 779.
