Show of the other tests performed with ambient air preheat. A similar comparison is given in Figure 6 for test 12. As seen in the figures, the tests demonstrated the potential for utilizing the advanced burner as a low-NOx oil-fired burner. The figures show corrected NOx emissions of 146 ppmvd for test 11 and 157 ppmvd for test 12. Both tests had CO emissions less than 10 ppmvd. These results are comparable to commercially available 10w-NOx oil-fired burners. The overall performance of the advanced burner was found to be superior to that of the Zink HPS™ burner. The NOx emissions decreased by 20 to 30 percent on No.6 fuel oil, with minimal CO production. The DRE calculated for the advanced burner also appeared to be superior, and exceeded 99.995 percent in all cases except test 3. However, the HPS™ burner did demonstrate slightly lower THe emissions when firing No.6 fuel oil. The THC results could be a concern due to the 20 ppmvw limit for THe emissions from BIFs. However, the 20 ppm limit is the incremental increase associated with firing the waste liquid, and is added to the baseline THe emissions for the boiler without waste liquid firing. Thus, if the unit produces 20 ppmvw THC firing its normal fuel, the THC limit would be 40 ppmvw while fIring waste liquid. The measurement of the DRE is the primary point of comparison, and the advanced burner exceeded the regulatory requirement of 99.99 percent removal in every test. FUTURE WORK During Phase ill, a strategic plan will be developed for deploying the advanced burner into the marketplace. As part of this effort, burner manufacturers will be consulted to identify a teaming partner. In addition, a number of potential host sites will be contacted to determine those most suitable for commercial demonstration of the advanced burner. At the completion of this planning and teaming task, the marketplace will be reassessed to determine if there is sufficient cause to continue the advanced burner program. The product of this task will be a 13 |
