The report gives results of the final phase of a program to develop, demonstrate, and evaluate a low-NOx burner for crude-oil-fired steam generators used for thermally enhanced oil recovery (TEOR). The burner designed and demonstrated under this program was developed from design criteria established in bench- and pilot-scale experiments. The report describes the successful installation and testing of a full-scale (16 MWt) commercial prototype burner in the Kern County, CA, oil fields on a conventional TEOR steam generator. A 30-day continuous monitoring test demonstrated the capability of the burner to continuously maintain NOx emissions of 70 ppm with CO emissions below 50 ppm and particulate emissions below 0.23 g/dscm. Detailed emission measurements also showed negligible emissions of organic species, including EPA priority pollutants. Thermal efficiency of the steam generator was similar to that prior to the low-NOx retrofit and was within the normal range for conventional steam generators. The mechanical performance of all major burner components was satisfactory.
