Abstract
A method for removing electrostatically charged particles that are difficult to separate from a gas flow within one or more high-voltage fields, wherein only one high-voltage supply source is used for these high-voltage fields. The flows to be cleaned are successively ionized in an ionizing region and the particles are separated in a separating region within the one or more high-voltage fields, wherein the field strength of the ionizing region is weaker than the field strength of the separating region.
