摘要： A system and method for flame stabilization is provided that forestalls incipient lean blow out by improving flame stabilization. A combustor profile is selected that maintains desired levels of power output while minimizing or eliminating overboard air bleed and minimizing emissions. The selected combustor profile maintains average shaft power in a range of from approximately 50% up to full power while eliminating overboard air bleed in maintaining such power settings. Embodiments allow for a combustor to operate with acceptable emissions at lower flame temperature. Because the combustor can operate at lower bulk flame temperatures during part power operation, the usage of inefficient overboard bleed can be reduced or even eliminated.

摘要翻译：提供了一种用于火焰稳定化的系统和方法，其通过改善火焰稳定性来防止初始稀薄吹出。选择燃烧器型材，其保持期望的功率输出水平，同时最小化或消除舷外排气并最小化排放。所选择的燃烧器型材将平均轴功率保持在大约50％到全功率的范围内，同时在保持这种功率设置的同时消除舷外空气泄漏。实施例允许燃烧器在较低火焰温度下以可接受的排放物操作。因为在部分动力运行期间燃烧器可以在较低的主体火焰温度下操作，所以可以减少甚至消除无效率的舷外排放的使用。
