SER& Project Summary
Flue Gas Desulfurization
Information System (FGDIS)
Data Base User's Manual
Michael T. Melia
This document is a user's manual and
reference book/primer for Flue Gas
Desulfurization Information System
(FGDIS) users and recipients of the
quarterly Utility FGD Survey. Part I is
the interactive computer procedures for
the FGDIS; it addresses the use of and
terminology related to the use of the
computerized data base. Part II is the
FGDIS terminology; it addresses FGD
technology as it relates to this com-
puterized data base. The primary thrust
of Part II concerns equipment/compo-
nent classifications: major equipment
items and construction materials are
broken down into primary, secondary,
and tertiary categories referred to as
generic type, specific type, and trade/
common name (or common design).
These are supported by an appendix
that describes the use of the problem/
solution codes. A glossary defines
common scrubber and boiler-related
FGD terms, including definitions of data
field titles in FGDIS that may be unclear
to new FGDIS users or individuals
somewhat detached from the system.
The Utility FGD Survey, a major
product of the FGDIS, is available
through the Research Reports Center
of the Electric Power Research Institute
(EPRI), Palo Alto, CA (415/965-4081).
The Survey includes a significant por-
tion of the information collected within
the FGDIS; however, important data
(e.g., dependability, cost, specific de-
sign) are not included and can only be
obtained through access of the FGDIS.
This Project Summary was developed
by EPA's Air and Energy Engineering
Research Laboratory, Research Triangle
Park, NC, to announce key findings of
the research project that is fully docu-
mented in a separate report of the same
title (see Project Report ordering infor-
mation at back).
Introduction
Utilities in the U.S., operating or plan-
ning to install flue gas desulfurization
(FGD) systems, are contacted regularly
throughout each year to provide data that
constitute the basis for the Utility FGD
Survey.
The quarterly Survey is generated by a
computerized data system known as the
Flue Gas Desulfurization Information
System (FGDIS). Figure 1 (see pages 4
and 5), a structure diagram of the FGDIS,
shows the informational areas addressed
in the system and some representative
data items contained in each. The design
data contained in the system encompass
the entire emission control system and
the power generating unit to which it is
applied. Performance data for operational
FGD systems include monthly depend-
ability parameters, along with service
time and problem/solution descriptions.
In addition to generating the Survey,
the FGDIS is available for remote terminal
access. Because the Survey is available
through purchase from the National
Technical Information Service (NTIS)
(after June 1983, it may be purchased
from Electric Power Research Institute
(EPRI)), the data base is the most immedi-
ate method for examining the data ac-
quired under the survey program. Access
to the FGDIS also enables users to obtain
data that are too specific for inclusion in
the Survey. Information concerning ac-
cess to the FGDIS can be obtained from

of the FGDIS data can also be arranged.
Part I: Interactive Computer
Procedures for the FGDIS
This manual is a guide to the use of the
FGDIS, a collection of data base files
stored at EPA's National Computer Center
(NCC) in Research Triangle Park, NC.
These files are accessed and their data
are manipulated using SYSTEM 2000®, a
general data base management system
developed by INTEL Corporation and
supported by NCC's Univac 1100 hard-
ware.
The FGDIS is a collection of data files
pertaining to the design, performance
(S02 and dependability), and cost of FGD
systems. The data stored as logical entries
(elements), linked by a common structure
consisting of various levels of repeating
groups (or levels of information). Figure 1
shows the FGDIS structure, along with
some key data items. A given FGD system
may have as many as 574 design data
entries (14 of which are cost-related) and
74 monthly performance data items.
(NOTE: The FGDIS can address any FGD
system design; not all data entry fields are
applicable to every FGD system.)
To access the FGDIS, a user must be
able to log into the Univac system at NCC.
This requires a telephone and coupler
modem, unless using a terminal that is
wired directly to the system (e.g., the
onsite terminals at NCC). The terminal
also must be compatible with the Univac
1100 system. Any terminal, hard copy, or
cathode ray tube (CRT) that emulates a
Teletype at 30 or 120 bits per second can
be supported. The terminal, however,
must use the ASCII character set and be
set in the half-duplex mode (one-way
telecommunication between terminal and
computer).
Compatible terminals include: (1)
Anderson Jacobson 63x, 83x; (2) Hazel-
tine 1000, 2000 (CRT); (3) Hewlett-Pack-
ard 2622A; (4) Sperry Univac DCT 500,
1000, Uniscope 100 (DCT 1000s and
Uniscope 100s can be supported only
over dedicated circuits in synchronous
mode); (5) Tektronix 401 x, 4051; (6)
Teletype 33, 35, 37, 38 (ASR/KSR); and
(7) Texas Instruments 7xx, 770/2. They
do not include all available compatible
terminals, nor do they represent recom-
mended terminals. More than 100 manu-
facturers produce hardcopy and CRT
terminals, and as long as a terminal can
emulate a teletype, it can be supported.
Access to the NCC system is available
to 300- and 1200-baud (baud is a variable
unit of data transmission speed, usually
equal to 1 bit per second) users through a
nationwide telephone communications
system (TYMNET) that offers local dialing
numbers in more than 100 cities; WATS
service is available to those for whom
local numbers are not available.
Actual charges for on-line access de-
pend on the type of retrieval commands
used. A simple command to print a report
may cost only $10; whereas, a more
sophisticated statistical analysis of the
data base may cost $150. Users are
charged only for the computer resources
used, not actual on-line computer connect
time. There is no charge for obtaining an
account number.
The user's manual shows in detail NCC
access (computer log-on/log-off), Sys-
tem 2000 execution/termination, imme-
diate access features, the report writer
Table 1. Available Report Writer Programs

Program
(canned program) feature, and output
control.
The immediate access feature describe;
the execution of extensive cross refer
encing possibilities, with examples. I
includes formatting options and systerr
functions (e.g., addition, subtraction
multiplication, division, averaging, stan
dard deviation, and maximum/minimurr
value).
The report writer feature illustrate;
System 2000's ability to prepare standan
report programs that may be used (it
conjunction with the immediate access
feature) to exclude or include specifii
subsets within the FGDIS files.
Also included in Part I are nine appen
dices. Appendix A, which lists the nim
report writer programs prepared to date
contains an abstract illustrating the usi
of the program, a sample run strean
(what the user would type in), a sampl
output, and other suggested uses/com
ments. Table 1 lists the available repor
writer programs, along with brief descrip
tions.

tional, under construction, contract awarded, planned) as well as salable v
throwaway product designs.

utilization) as well as capacity factors, boiler hours, FGD system operating houi
and hours for the time period and unitfs) specified.
ABSTCT Generates a brief abstract for units specified in addition to unit megawatt ratin
location, boiler and FGD system type, FGD process utilized, etc.

Table 2 shows examples of run streams
and sample outputs of two report writer
programs, PERAVG and ABSTCT. The
nine appendices are described briefly in
Table 3.
Part II. FGDIS Terminology
This section discusses terminology
used in the FGDIS, in both tabular and
graphic form.
Part II covers 12 major equipment/
component classifications for FGD sys-
tems, as categorized in the FGDIS: (1)
scrubbers/absorbers; (2) mist elimina-
tors; (3) reheaters; (4) solids dewatering
devices; (5) sludge processors; (6) sludge
disposal sites; (7) reagent preparation
equipment; (8) pumps; (9) valves; (10)
dampers; (11) construction material; and
(12) fans.
Each section shows a breakdown in
three categories: generic type, specific
type, and trade/common name (or com-
mon design). Exceptions to this categor-
ization are valves (addressed only as
generic and specific) and fans (classified
separately).
The sixth group, sludge disposal sites,
is used as an example. Table 4 gives a
breakdown of generic, specific, and
common design types of sludge disposal
sites. Figure 2 presents typical graphic
representations of one of these generic
types, the pond.
Each item in Table 4 is described in a
short paragraph. Similar brief descrip-
tions are given in the text throughout Part
II.
