Abstract
The present invention describes a method and an arrangement for purifying the intake air of a gas turbine of solid particles and liquid droplets. According to the invention air is taken into the system of intake air passages (1, 2, 4) of the gas turbine and the particles contained in the intake air are collected by means of at least one plate filter (3) to which a collection voltage has been connected. In order to enable and enhance collection, the air is taken into at least one charging chamber (2) arranged at a distance prior to the plate filters (3) in the flow direction of the air, where an electric field is formed between at least two electrodes (5, 7) by connecting a voltage between the electrodes which exceeds the collection voltage, whereby powerful charging of the particles and at least partial removal of the water contained in the air are effected.
