摘要： The primary nozzles of a Dry Low NOx (DLN) combustor are configured to alternatively burn a first gas fuel or a second gas fuel, where the two gas fuels may have widely disparate energy content. Natural gas may be the first gas fuel and syngas may be the second gas fuel. An inner fuel circuit and an outer fuel circuit are provided to allow effective control of fuel/air mixing profiles, dynamics, primary pre-ignition and emission control by changing the fuel split between the two fuel circuits. The inner fuel circuit may be run in a diffusion combustion mode on many gas fuels.
摘要翻译：干式低NOx（DLN）燃烧器的主喷嘴被配置为交替地燃烧第一气体燃料或第二气体燃料，其中两种气体燃料可能具有广泛不同的能量含量。天然气可能是第一种天然气燃料，合成气可能是第二种天然气燃料。提供内部燃料回路和外部燃料回路以通过改变两个燃料回路之间的燃料分配来有效地控制燃料/空气混合曲线，动力学，初级预点火和排放控制。内部燃料回路可以在许多气体燃料的扩散燃烧模式下运行。

摘要： A combustor for a gas turbine engine includes a plurality of primary nozzles configured to diffuse or premix fuel into an air flow through the combustor; and a secondary nozzle configured to premix fuel with the air flow. Each premixing nozzle includes a center body, at least one vane, a burner tube provided around the center body, at least two cooling passages, a fuel cooling passage to cool surfaces of the center body and the at least one vane, and an air cooling passage to cool a wall of the burner tube. The cooling passages prevent the walls of the center body, the vane(s), and the burner tube from overheating during flame holding events.
