EPA Project Summary
Proceedings: 1991
Joint Symposium on Stationary
Combustion NO,. Control
Carolee DeWitt
The 1991 Joint Symposium on Sta-
tionary Combustion NOX Control was
held March 25-28,1991, in Washington,
DC. This symposium, jointly sponsored
by the Electric Power Research Insti-
tute (EPR1) and the U.S. Environmental
Protection Agency (EPA), was the sixth
in a biennial series devoted to the in-
ternational exchange of information re-
garding recent technological and regu-
latory developments pertaining to sta-
tionary combustion nitrogen oxides
(NO*) control. Topics discussed in-
cluded the significant increase in ac-
tive full-scale retrofit demonstrations
of low-NOx combustion systems in the
U.S. and abroad over the past 2 years;
full-scale operating experience in Eu-
rope with selective catalytic reduction
(SCR); pilot- and bench-scale SCR in-
vestigations in the U.S.; increased at-
tention on selective noncatalytic reduc-
tion (SNCR) in the U.S.; and NOX con-
trols for oil- and gas-fired boilers.
This Project Summary was developed
by EPA's Air and Energy Engineering
Research Laboratory, Research Tri-
angle Park, NC, to announce key find-
ings of the research project that is fully
documented in a separate report of the
same title (see Project Report ordering
information at back).
The Symposium
The 4-day meeting was attended by
approximately 500 individuals from 14 na-
tions. Sixty-six papers were presented by
EPRI and EPA staff members, domestic
and foreign utility companies, federal and
state government agencies, research and
development organizations, equipment
vendors from the U.S. and abroad, and
university representatives.
The Proceedings are compiled in three
volumes. Volume 1 contains papers from:
• Session 1: Background
• Session 2: Large Scale Coal Com-
bustion I
• Session 3: Large Scale Coal Com-
bustion II
Volume 2 contains papers from:
• Session 4A: Combustion NOX Devel-
opments I
• Session 4B: Large Scale SCR Appli-
cations
• Session 5A: Post Combustion Devel-
opments I
• Session 5B: Industrial/Combustion
Turbines on NOX Con-
trol
Volume 3 contains papers from:
• Session 6A: Post Combustion Devel-
opments II
• Session 6B: Combustion NOX Devel-
opments II
• Session 7A: New Developments I
• Session 7B: New Developments II
• Session 8: Oil/Gas Combustion Ap-
plications
An appendix in Volume 3 lists sympo-
sium attendees.
