Evaluation and Demonstration of Low NOx Burner Systems for TEOR Steam Generators. Test Report: Preliminary Evaluation of Commercial Prototype Burner

摘要

The report documents preliminary testing of a 16 MW low-NOx burner for retrofit application to thermally enhanced, oil recovery steam generators. The burner is designed to achieve NOx emissions below 85 ppm (at 3 percent O2) while burning heavy fuel oil containing more than 0.6 weight percent bound nitrogen. The design of this burner (documented in a companion report) is based on optimizing conditions of stoichiometry, temperature, and residence in a separate, regeneratively cooled prechamber. This preliminary evaluation demonstrated the ability of the burner to produce very low NOx levels on a high nitrogen residual oil, with low smoke and CO emissions, and with a flame which appears to be compatible with steam generators. Final optimization and detailed evaluation of the burner hardware and control system will take place during the field evaluation phase of this program.
