  • Patent number: 8038776
    Abstract: An inlet air filtration system for a gas turbine includes, in an exemplary embodiment, an air plenum, and a plurality of filter elements mounted inside the air plenum, with each filter element including a support structure. The inlet air filtration system also includes a plurality of electrodes positioned proximate the plurality of filter elements, where the electrodes are coupled to a power source which supplies a voltage to the electrodes. The voltage is sufficient to establish an electrostatic field between the electrodes and the filter elements, and is sufficient to produce a corona discharge from the electrodes, wherein an amount of current applied to the filter elements is about 0.1 ?A/ft2 to about 15 ?A/ft2.
    Type: Grant
    Filed: March 23, 2010
    Date of Patent: October 18, 2011

  • Patent number: 7527674
    Abstract: An inlet air treatment system for a gas turbine includes, in an exemplary embodiment, an air plenum, and a moisture removal system, and an air filtration system located downstream from the moisture removal system. The moisture removal system includes a plurality of S-shaped vanes, and a mesh structure downstream from the plurality of S-shaped vanes. The air filtration system includes a plurality of filter elements, with each filter element including a support structure. The inlet air filtration system also includes a plurality of electrodes positioned proximate the plurality of filter elements, where the electrodes are coupled to a power source which supplies a voltage to the electrodes. The voltage is sufficient to establish an electrostatic field between the electrodes and the filter elements, and at the same time, the voltage is sufficient to produce a corona discharge from the electrodes.
