Purge Air Systems

New emission regulations are requiring that you maintain compliance during all operations, including start up and shut downs. For operators of precipitators, this represents a challenge in mitigating exposure to the risk of damaging equipment during these events. Purge air systems can help you reduce this risk, allowing you to increase your operational flexibility.

Many ESPs require a purging system to prevent dust from migrating into the high-voltage insulator enclosures. Most conventional purge systems are ineffective, costly to operate and maintain, and can’t adapt operations to conditions. A properly operating system ensures that high-voltage insulators are kept dry, preventing tracking and failures, and heated systems prevent dew-point corrosion. These issues can lead to performance degradation or even sections being taken offline.

The greatest potential cost of a sub-optimal purge system is failure of ESP sections due to tracking, cracking, and failed insulators which cause an increase in emissions or reduced load availability. With today’s tight emissions operating parameters, these performance set-backs can have large impacts.

Unlike conventional systems, the Neundorfer SmartPurge system uses a common-sense control system that economically accommodates varying electrostatic precipitator conditions. It maintains proper purge flow and temperature, preventing both dust migration and tracking or failing insulators.

The Neundorfer PLC-based SmartPurge system efficiently maintains a specific velocity of heated purge airflow from the insulator enclosures into the ESP chamber. We offer our standard system for most applications, as well as custom-designed systems for unique needs and applications.
