Abstract: An electrostatic precipitator for introducing sub-millimeter sized particles into a carrier material. The carrier material has a melting point which lies above 0° C., preferably above room temperature. The electrostatic precipitator comprises a casing having an inlet for inserting a gas flow into the casing and having an outlet for guiding a gas flow out of the casing. A channel for passing the gas flow from the inlet to the outlet is provided. A discharge electrode is provided on a first side of the channel. A collecting electrode is provided at a second side of at least a part of the channel. The electrostatic precipitator applies an electric field between the discharge electrode and the collecting electrode. A receiving volume is provided with a molten material as carrier material.
