The central portion of the electrode has one or more discharging portions in a path for the flow of pulverulent or gaseous material toward a deflector which is releasably mounted at the front end of the inner tube. The electrode is connected with a high-voltage conductor which is mounted in a tubular shield within the inner tube.
