Common Inspection Issues with Electrostatic Precipitators - AirTek
Updated: Nov 18
Your electrostatic precipitator keeps your operation compliant with local and federal environmental protection guidelines. But maintaining your electrostatic precipitator can sometimes become an afterthought, leading to diminished performance and compounding issues.
At AirTek, we know it’s not always easy to keep on top of daily checks and performance monitoring. But your ESP is too vital to neglect. These are the most common issues discovered in electrostatic precipitators during inspection that you may be able to prevent with regular maintenance and diligence.
Typically speaking, dust removal systems can be often overlooked. As a critical component in the daily operation of your electrostatic precipitator, the continued, strong function of your dust removal system keeps your ESP healthy. If the dust removal system ceases to function the ESP can ground out and shut down your operation.
Since dust accumulation can contribute to a cascade failure of other components in your ESP, it’s vital that you stay on top of regular maintenance. If you suspect that a component of your dust removal system is failing to meet reliability expectations, it may be time to call in the pros.
Buildup on Collection Plates
Another threat to your precipitator comes in the form failed rappers. Failure to inspect or maintain the rapping system will leave the collection plates covered in dust. This dust covering will reduce the effectiveness of the charged particles migrating to the grounded collection plates. As time goes on this effect will become worse and worse, eventually causing the ESP to be no longer effective.
Rapping effectiveness on ESP plates is a snowballing issue—one that needs your attention (or the attention of professionals) straight away.
Most modern electrostatic precipitators feature rigid frames and rigid electrodes, providing an extended electrode life. Many ESPs in use today may be retrofitted with these upgrades or still have wire discharge electrodes. Electrode failures aren’t a guarantee in older ESPs, but they do have a greater chance of developing if your electrostatic precipitator has been operating for a decade or more.
Depending on where the electrode failure occurs, it can lead to diminished performance or out-and-out failure, compromising the daily operation of your electrostatic precipitator and leading to other, chronic issues such as those listed above. If these breakages are happening more than occasionally, it is time to upgrade your system.
