Electrostatic Precipitator Maintenance

in

Electrostatic Precipitators (ESPs) require minimal maintenance since there are essentially no "moving parts" to wear out. However, proactive preventive maintenance and basic monitoring of the ESP will prolong its life indefinitely and provide good performance while meeting compliance standards.

Monitoring

High Voltage Energization System Maintain proper operation of the high voltage energization system Always make sure the high voltage energization system is operating properly. This includes the high voltage controls and transformer-rectifiers. The high voltage system of the electrostatic...

ESP Ozone

What is Ozone? Ozone (O3) is created by passing an electrical current through air.  Ozone is created inside an Electrostatic Precipitator when the ESP is energized under an "air" load. Electrostatic Precipitator Ozone Safety An electrostatic precipitator creates appreciable amounts...

General ESP Safety

Follow all plant safety rules Make sure all ground switches are in good condition and properly used Follow all confined space requirements Follow the safety key interlock system

Precipitator Troubleshooting

Most problems are identified by an alarm. All alarms should be proven/verified and addressed. The common ESP problems and causes are as follows: Symptom Cause Solution Under voltage trip or low voltage Full hopper Broken, tracking or cracked insulator Internal electrode misalignment Make...

Electrostatic Precipitator Operation

Process Conditions Maintain proper process conditions (i.e. boiler operation). Upset conditions in the process will affect the performance of the Electrostatic Precipitator. Also, avoid thermal excursions or other similar conditions that may cause damage to the ESP (such as operating above design...
