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.
