The proceedings document presentations at the 1989 Joint Symposium on Stationary Combustion NOx Control, held March 6-9, 1989, in San Francisco, CA. The symposium, sponsored by the U.S. EPA and EPRI, was the fifth in a series devoted solely to the discussion of control of NOx emissions from stationary sources. Topics discussed included low-NOx combustion developments such as burner design modifications and reburning; coal-, oil-, and gas-fired boiler appliclications; flue gas treatment processes; fundamental combustion studies; and industrial and commercial applications. Also presented were manufacturers' updates of commercially available technology and an overview of environmental issues involving NOx control. Volume 2 includes SCR coal applications, fundamental combustion research, post combustion NOx control development, fundamental combustion research, new developments, and oil and gas combustion.
