Abstract |
The article summarizes information presented at the 1989 Joint EPA/EPRI Symposium on Stationary Combustion NOx Control, March 6-9, 1989, in San Francisco. The symposium was attended by more than 400 representatives of 40 domestic and 10 foreign utilities, government agencies, research and development organizations, and boiler manufacturers from the U.S. and 14 other nations. More than 60 presentations focused on developments in combustion NOx technologies, selective catalytic reduction (SCR), advanced combustion technologies, hazardous and municipal waste incineration, combined NOx/SO2 control processes, and fundamental combustion research. Introductory reports covered the NOx regulatory status in the U.S. and abroad, the U.S. DOE's Innovative Clean Coal Technology program, and NOx measurements and environmental effects. Key points discussed included the dramatic increase in full-scale retrofit demonstrations of low-NOx combustion modifications on pulverized-coal-fired boilers; full-scale operating experience in Japan and Western Europe with SCR, and research and development to assess application in the U.S.; and development of NOx controls for utility boilers.
