Apparatus for filtering gas turbine inlet air

A gas turbine apparatus, said gas turbine apparatus comprising:

• a compressor;
• an air inlet coupled to said compressor;
• a combustor coupled to said compressor;
• a turbine coupled to said combustor;
• an exhaust duct coupled to said turbine;
• an air plenum coupled to said air inlet;
• and
• an air treatment system positioned in said air plenum, said air treatment system comprising:
• a moisture removal system positioned inside said air plenum;
• and
• an air filtration system positioned inside said air plenum and located downstream from said moisture removal system;
• said moisture removal system comprising:
• a plurality of S-shaped vanes mounted inside said air plenum, said S-shaped vanes defining a serpentine flow path;
• and
• a mesh structure mounted inside said air plenum downstream from said plurality of S-shaped vanes;
• said air filtration system comprising:
• a plurality of filter elements mounted inside said air plenum, each said filter element comprising a support structure;
• and
• a plurality of electrodes positioned proximate said plurality of filter elements, each said electrodes coupled to a power source which supplies a voltage to said electrodes, said voltage sufficient to establish an electrostatic field between said electrodes and said filter elements, and said voltage sufficient to produce a corona discharge from said electrodes.
