Download or read book Effect of Flame Stabilizer Design on Performance and Exhaust Pollutants of a Two row Swirl can Combustor Operated to Near stoichiometric Conditions written by James A. Biaglow and published by . This book was released on 1977 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Emissions and performance characteristics were determined for two full annulus modular combustors operated to near stoichiometric fuel air ratios. The tests were conducted to obtain stoichiometric data at inlet air temperatures from 756 to 894 K and to determine the effects of a flat plate circular flame stabilizer with upstream fuel injection and a contraswirl flame stabilizer with downstream fuel injection. Levels of unburned hydrocarbons were below 0.50 gram per kilogram of fuel for both combustors and thus there was no detectable difference in the two methods of fuel injection. The contraswirl flame stabilizer did not produce the level of mixing obtained with a flat plate circular flame stabilizer. It did produce higher levels of oxides of nitrogen, which peaked at a fuel air ratio of 0.037. For the flat plate circular flame stabilizer, oxides of nitrogen emission levels were still increasing with fuel air ratio to the maximum tested value of 0.045.

This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Combustion instabilities in gas turbines are associated with increased pollutant emissions, inconsistent power or thrust output, and premature wear and failure of components. Combustion instabilities arise from a feedback loop between resonant combustor acoustics and flame heat release rate oscillations and are especially of concern in modern lean-premixed combustor systems. This thesis considers the suppression mechanisms and efficacy limits of two techniques used to mitigate combustion instability: fuel staging and central piloting. Fuel staging, a technique in which the equivalence ratio of a multi-nozzle combustor is unevenly distributed between the nozzles, has been shown to mitigate the intensity of self-excited combustion instabilities in multiple nozzle combustors. Foundational work to this thesis explored the suppression mechanism of a combustor stabilized by fuel staging via an edge-tracking algorithm applied to high-speed planar video of adjacent flame edges, revealing that fuel staging de-phased adjacent flame edges, breaking the instability feedback loop. A nozzle for which fuel staging exhibited relatively lower efficacy in comparison to the other nozzles of the combustor was also investigated; this differences in efficacy was attributed to a minor variation in nozzle hardware. Central piloting suppresses combustion instability via the addition of a central torch-shaped pilot flame along the central axis of a larger main flame. The pilot flame has previously been shown to improve the static stability of the main flame by providing a source of heat and radical chemical species near the main flame base. However, the presence of the pilot flame may also enhance an instability in certain cases. This thesis studies the mechanisms and flame dynamics associated with central piloting both in cases where piloting was effective at stabilizing the combustor and in cases where the stability outcome was worsened by piloting. By studying the efficacy limits of instability suppression techniques, this thesis aims to contribute to improved thermoacoustic design tools and injector designs.
