  • Arrangement in emitting electrodes for electrostatic precipitators
    Patent number: 4106919
    Abstract: In an electrostatic precipitator, the emitting electrodes consist of helically wound wire, and are extended and attached in the space between the collecting plates, and have a non-round cross-section. In each of the electrodes has a long axis approximately twice the short transverse axis in order to increase the mechanical strength against electric erosion and simultaneously maintain an optimum of current distribution (corona) from the electrodes.
