Abstract
The "Electrostatic Precipitator Maintenance Guide" is directed towards electrical and maintenance personnel who maintain the electrostatic precipitator (ESP) and troubleshoot problems that occur during operation. The intent of this guide is to give plant personnel guidelines for maintaining an ESP for reliable operation.
Background
With increased restrictions on emission requirements and cutbacks in personnel that have been happening in the industry over the past several years, more responsibility of daily operation and maintenance of the precipitator falls into the hands of electrical and maintenance personnel. These personnel therefore need a better understanding of the precipitator system and how its operation affects the entire plant.
Objective
o To give a basic understanding of the fundamental theory and principles of electrostatic precipitation.
o To provide guidelines on routine maintenance to maintain and improve the reliability and performance of the precipitator system.
o To have a quick and easy reference for plant personnel on the maintenance requirements for each component of the system.
o To give a basic understanding of how system changes can affect precipitator operation.
Approach
The content of this guide came mainly from the practical experience of the author and associates, as well as from available guides that include past EPRI publications. A survey was sent to Fossil Maintenance Applications Center (FMAC) members to have them identify specific ESP maintenance issues experienced at their plant/utility. The results of this survey helped in determining which issues were important to discuss in the guide.
Results

The guide includes information on the following topics:

o Background of ESPs
o ESP components and term
o ESP theory
o Process effects on ESPs
o Maintenance practices
o On-line diagnostics
o Off-line diagnostics
o ESP components
o Control and instrumentation
o Penthouse/weather enclosure area components
o Hopper area
o Ductwork and casing
o ESP internals
o Safety system
o ESP maintenance program
o Outage maintenance planning
o Safety
o Effects of boiler system equipment and system modifications

Volume 1 (1007436) of this two-volume set (E213676) contains Sections 1-4. Volume 2 (1007690) contains Sections 5 and 6 and the appendices.

EPRI Perspective
Providing plant personnel with accurate information concerning the maintenance of ESPs and the operational effects on them may prevent unneeded maintenance or forced outages from occurring on the equipment. The primary objective of the guide is to aid plant personnel in maintaining the ESP and all its associated components/systems. The guide focuses on providing detailed operational, testing, maintenance, and troubleshooting techniques on ESPs.
