Repair and maintenance
ESP work
Mechanical work on electrostatic precipitators: electrodes, rappers, hoppers and casing, set to the alignment that keeps dust capture high.

Working principle
How it works
The working process in four steps.
Dusty gas enters
Screens spread the flue gas evenly across the ESP.
Dust takes a charge
Discharge electrodes charge the particles in the gas.
Plates collect it
Charged dust sticks to the collecting plates.
Rappers knock it down
Hammers shake the plates and dust falls to the hoppers.
