The invention relates to a method and an arrangement for cleaning the intake air to a compressor of a gas turbine employed in energy generation. Conventionally, mechanical fabric filters are used as the intake air filters of gas turbines. As known, fabric filters are capable of separating particulates of relatively large size only from the air, whereby a portion of the contaminating particles suspended in the air may enter the equipment causing dirt build-up therein. By virtue of the present invention, the intake air can be cleaned at a higher degree of efficiency using a method according to which the mechanical filtering stage of the intake air is combined with at least one electrostatic filtering stage and a complementary stage in which the electrical properties of particulates suspended in the air are improved electrically or chemically. |
