The current in both the primary and secondary stages of the wet electrostatic dust removal system is very low
Thread Content
The wet electrostatic precipitator has been working well, but suddenly, with the voltage remaining unchanged, both the primary and secondary currents dropped to single-digit values. What could be causing this?
Excessive coal ash on the electrode wire hinders the proper discharge for dust removal in electrostatic precipitators; it is necessary to flush it or shut down the equipment for cleaning.
