ABSTRACT A corona discharge apparatus includes a corona elec- trode (K) and a target electrode (M) which is spaced from the corona electrode (K). The electrodes are con- nected to a d.c. source (2) having a voltage such as to produce a corona discharge on the corona electrode. For the purpose of removing the harmful or irritating gase- ous substances generated by the corona discharge, there is provided a suction channel (4) which has an inflow opening or orifice (4a) located in the immediate vici- nity of the corona electrode (K). The remainder of the suction channel is delimited in relation to the space (1) housing the corona electrode and the target elec- trode. Mounted in the suction channel (4) or at a loca- tion adjacent the channel opening (4a) is an additional electrode (E), which is connected to a d.c. potential which, in relation to the potential of the corona elec- trode (K), has the same polarity as the potential of the target electrode (M), so that an ion current will occur from the corona electrode (K) to the additional electrode (E), and therewith give rise to an airflow (8) past the corona electrode (K) and into the suction channel (4), through the channel opening (4a).
