Electronic corona may be obturated when dust load at inlet of ESP is more than 500g/Nm3, it will influence dedusting efficiency. Through analysis on current and electric intensity, we set up experiment device and use WS corona wire, fishbone corona wire, long dentation corona wire, V15 wire and RS corona wire to test their volt-ampere characteristics. This experiment indicates that the corona current produced by V15 and long dentation corona wires is higher, i.e. we can get higher corona current under same voltage to produce stronger corona discharge and electric wind, and it has little possibility to occur corona obturation in electric field. We can get the conclusion that V-typed corona wire is more suitable and economic for high dust load application.

Abstract This article presents the results of “electrical wind” investigations in CO2–laser mixtures at superatmospheric (1–12 atm) pressures. It is established that for a fixed value of the unipolar corona discharge current, the gas flow velocity does not depend on the pressure, but is determined by the chemical composition of the working mixture. The maximum values of the “electrical wind” velocity are achieved in carbon dioxide and molecular nitrogen and their values are 3.2 and 2.9 ms−1. In typical laser mixtures CO2:N2:He = 1:1:1 – 1:1:3 the velocity of the “electrical wind ” are in the range from 2.5 to 1.5 ms−.
