Fly ash resistivity
WebWithin the range of normal dust resistivity (between 10 7 and 2 × 10 10 ohm-cm), fly ash is collected more easily than dust having either low or high resistivity. High resistivity [ edit] If the voltage drop across the dust layer becomes too high, several adverse effects can occur.
