Electrostatic Precipitators for Air Pollution
Control
Raymond Ehrhard, P.E.
Overview
An electrostatic
precipitator (ESP) is a pollution control device that uses electrical forces to
move the particles out of the flowing gas stream and onto collector plates for
particulate emission control.
There are different configurations and types of
ESPs designed and operated for removal of particulate mater (PM). This course
describes the commonly applied ESP designs used to remove PM from stationary
sources. Design and operating parameters are presented. Various ESP designs such
as Plate-Wire, Flat Plate, Wet ESPs, and Tubular ESPs are reviewed in this
course.
In this course the student will learn the theory
of ESP particle removal and how it is applied to actual ESP designs. The
conditions for particle removal and its effects on ESP equipment selection are
presented. Optimizing ESP operation is also presented. The course will be
beneficial for a student with basic knowledge of air pollution control equipment
and an interest in controlling particulate emissions. It is also an excellent
overview for those professionals working in the field of air pollution control.
The student is expected to read and review the material contained
in EPA Air Pollution Control Cost Manual Section 6 –Particulate Matter
Control, Chapter 3 – Electrostatic Precipitators, (EPA 452/B-02-001).
The
student must take a multiple-choice quiz consisting of thirty (30) questions at the end of
this course to obtain PDH credits.
