Show stream appears to cause high NOx emissions and the operators reduce the flow rate. Average NOx formation is 0.17 lbs / million BTU and normal stack concentratration is 70 to 80 ppm NOx. The chlorine content of the liquid and solid feed streams needs to be considered when comparing NOx emissions from various incineration facilities. Acknowledgement Thanks to Drs. David Pershing and Warren Owen of Reaction Engineering International for technical assistance on the NOx problems during the plant startup. Thanks to Gad Williams and Blake Beckstrom of Ford Bacon & Davis for the background information on other incineration projects. Footnotes 1.
