Air filtration assemblies for gas turbine systems and methods for filtering intake air in gas turbine systems

A gas turbine system comprising:

• a compressor;
• and
• an air filtration assembly in fluid communication with the compressor, the air filtration assembly including:
• an air inlet duct including:
• an inlet for receiving intake air including intake air particles;
• and
• an outlet positioned opposite the inlet;
• a plurality of vane filters at the inlet of the air inlet duct;
• an array of fabric filters positioned in the air inlet duct, downstream of the plurality of vane filters;
• a silencer assembly positioned in the air inlet duct, downstream of the array of fabric filters, the silencer assembly positioned adjacent the outlet of the inlet duct;
• and
• an electrostatic component positioned in the air inlet duct, downstream of the array of fabric filters, the electrostatic component configured to charge the intake air particles that pass through the plurality of vane filters and the array of fabric filters.

A method for filtering intake air for a gas turbine system, the method comprising:

• flowing the intake air including intake air particles through:
• a plurality of vane filters positioned at an inlet of an air inlet duct in fluid communication with a compressor of the gas turbine system, and
• an array of fabric filters positioned in the air inlet duct, downstream of the plurality of vane filters;
• and
• charging the intake air particles included in the intake air flowing through the plurality of vane filters and the array of fabric filters using an electrostatic component positioned in the air inlet duct, downstream of the array of fabric filters.
