摘要： A fuel injector includes an annular main fuel nozzle received within an annular nozzle housing, a main nozzle fuel circuit having at least one annular leg, and a pilot nozzle fuel circuit. Spray orifices of the leg extend through the fuel nozzle and spray wells through the housing are aligned with the orifices. The nozzle is designed to generate sufficient static pressure differentials between at least two different ones of the spray wells to purge the main nozzle fuel circuit. Spray well portions may be asymmetrically flared out with respect to a spray well centerline in different local streamwise directions. Some of the spray well portions may be asymmetrically flared out in a local upstream direction and others in a local downstream direction. The local streamwise direction may have an axial component parallel to a nozzle axis about which the annular nozzle housing is circumscribed and a circumferential component around the nozzle housing.

摘要： A combustor module includes a pre-vaporizing chamber defined by an inner wall, and an outer wall, and a heat shield. The heat shield separates the pre-mixing zone from the reaction zone of the combustor. At least one fueling nozzle is disposed in the pre-vaporizing chamber for injecting fuel into the pre-vaporizing chamber. Fuel from the fueling nozzle is sprayed onto the surface of the heat shield, thereby simultaneously vaporizing the fuel and cooling the heat shield. The heat shield also includes a pilot fueling spray opening to allow fuel to pass directly into the reaction zone of the combustor to provide a piloting flame stability region therein.

摘要： The invention relates to a burner (100) having a combustion air duct (104), in which a swirl generator (109), which is formed from a number of swirl generator elements (108), is arranged in such a way that the swirl generator (109) can increase the mean velocity at which combustion air (112) flows through the swirl generator (109) to a Mach number of at least 0.4. This results in flow-acoustic decoupling of the combustion area from the combustion-air feed area.

摘要： A pre-mixture forming swirler in a gas turbine pre-mixed flame type low NOx combustor is improved so as to accelerate mixing of fuel and air and to prevent the occurrence of flame stagnation and burning of components. In particular, a three-dimensional swirler is constructed such that each swirler vane (101a) is twisted from a hub side thereof to a tip side so that a fitting angle (null) of the tip side relative to the center axis (C) of the fuel nozzle (102) is larger than the angle (null) of the hub side. Thereby, while the angle (null) of the hub side is set smaller so that flame stagnation and burning of components resulted therefrom may be prevented from occurring, the angle (null) of the tip side may be selected so that the shearing flow necessary for appropriate mixing of fuel (F) and air (A) is obtained. Thus, favorable pre-mixing is achieved, life deterioration due to the burning etc. is prevented and combustion efficiency is enhanced.
摘要翻译：在燃气轮机预混合火焰型低NOx燃烧器中形成旋流器的预混合物得到改善，以加速燃料和空气的混合，并防止部件火焰停滞和燃烧。特别地，三维旋流器被构造成使得每个旋流器叶片（101a）从其轮毂侧扭转到尖端侧，使得尖端侧相对于中心轴线（C）的拟合角度（β）为燃料喷嘴（102）大于毂侧的角度（α）。因此，当轮毂侧的角度（α）设定得较小时，可以防止发生火焰停滞和由此产生的部件的燃烧，因此可以选择尖端侧的角度（β），使得为了获得燃料（F）和空气（A）的适当混合。因此，实现良好的预混合，防止由于燃烧等导致的寿命劣化，并且燃烧效率提高。
