Abrégé

The invention relates to an apparatus (10) for reducing particulate emissions from flue gases (S) in a batch-fuelled fire space (12) comprising a firebox (14), wherein the apparatus (10) includes an electrode (16) which can be arranged in the firebox (14) in the area of the flame (18) or in the immediate vicinity of the flame (18) in order to generate an electric field (E), an insulation (24) arranged so as to cover a part of the electrode (16), a power supply (22) for supplying a voltage to the electrode, a transformer (30) for converting a voltage level of the electricity supplied by the power supply (22) to a voltage level of 1-100 kV, preferably 10-30 kV, and a collector (25) for collecting charged particles (15), which can be arranged in the firebox (14) in the area of the flame (18) or in the immediate vicinity of the flame (18), wherein the apparatus (10) is configured to allow a leakage current of 0.001 mA 5.0 mA, preferably 0.1 mA 5.0 mA, most preferably 2.0 mA 3.0 mA, through the insulation (24) in order to charge particles (15), and the insulation (24) and the collector (25) are configured to act as collector surfaces for the charged particles (15), and the particles (15) are oxidized on the collector surfaces under the effect of the temperature. The invention also relates to a fire space and to a method.
