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.
