Precipitator Seminars



APC Network


Precipitator Seminars offers both public and in-house seminars in electrostatic precipitation. The primary objective of these seminars is to teach attendees how to better evaluate, operate, maintain and improve the performance of existing precipitators. Emphasis is on developing a practical understanding of the basic factors and determinants of precipitator operation and performance.


Precipitator Seminars are run by:

Public Seminars

ESP Operation and Maintenance Seminar Scope

The main focus of the operation and maintenance seminar is to provide attendees with sufficient methods and information to better operate, maintain and improve the performance of existing precipitators, particularly those that are marginally sized and face a multitude of field problems. Mr. T. Keeler conducts this fundamental seminar on the practical aspects of the precipitator. They explain how to understand the underlying concepts to make the overall system perform best, how the process factors control the electrical readings and how to correct many of the maintenance problems that occur in the field. They discuss detailed procedures for internal inspections, gas distribution improvement methods and rapping concepts. This basic presentation is especially suited for hands-on personnel, plant engineers, and operation and maintenance supervisors.



Time will be allotted to evaluate and solve specific ESP problems brought in by the attendees. It is expected that the attendees will be able to apply concepts learned during the first two days of the seminar toward the solutions of these problems. Time to discuss specific problems privately with individual attendees is also scheduled for a three hour period during the evening of the second day.

Attendees are encouraged to bring in the following information on their installations:

At least two sets of ESP panel electrical readings with related process data and instantaneous opacity chart.
Ratings of the transformer-rectifier sets.
Precipitator layout and sizing.
Layout of inlet gas distribution system.
Areas of maintenance problems.
Please note that this request for information is only to enhance the worth of the seminar to those with specific problems. Generic problem data will also be supplied by the lecturers during the course of the seminar.
