摘要： In order to realize a stable decrease in NOx, a gas turbine combustor is supplied which can reduce combustion vibration. A combustor (3) is provided with a first box body (30), which is installed outside an object body (20) such as a combustor basket (6), a transition piece (7) or a bypass duct (11) so as to form a first internal space (31) having a predetermined capacity; and a first throat (32) having a predetermined length which has one end (32a) open to a side wall (20a) of the object body (20) and has the other end (32b) open to a first internal space (31); wherein, a first resistive element (33) having a multiple number of through-holes is inserted and engaged to one end (32a). Fluid particles serving as vibration elements of combustion vibration caused in a combustion region are effectively trapped by the first resistive element (33) and at the same time resonate with the air of the first internal space (31) being connected through the first throat (32) and vibrate in the neighborhood of the first resistive element (33), thereby damping vibration amplitude thereof.

摘要： A gas turbine combustor in which a part or all of the wall of the combustor disposed within an intake chamber is formed as an acoustic energy absorbing member that can absorb the acoustic energy of a combustion variation generated within the combustor. The acoustic energy absorbing member is constructed of a thin corrugated plate in a circumferential direction, a high-temperature-proof perforated material, or a back plate disposed at the outside of a perforated plate in a radial direction with a distance from the perforated plate. It is also possible to provide a covering member at the outside of the acoustic energy absorbing member in a radial direction, for covering the acoustic energy absorbing member with a distance from the acoustic energy absorbing member. It is preferable that the acoustic energy-absorbing member and/or the covering member are reinforced with a frame that extends in a circumferential direction and/or a longitudinal direction.

摘要： A method and a device for burning fuel with air in a combustion chamber. The air is fed to the combustion chamber through at least one air inlet and the fuel is fed to the combustion chamber through a plurality of burners. Each burner has an associated delay time corresponding to a period of time after which an acoustic impulse in the combustion chamber causes a thermal impulse during combustion of the fuel fed through the burner. The feeding of the fuel through the burner is controlled in such a way that the delay times of the burners are substantially different from one another. The invention can be used on a combustion chamber of a gas turbine.

摘要： An air fuel mixer is disclosed having a mixing duct, a set of inner and outer counter-rotating swirlers adjacent the upstream end of the mixing duct, and a hub separating the inner and outer swirlers to allow independent rotation thereof, wherein high pressure air from a compressor is injected into the mixing duct through the swirlers to form an intense shear region and fuel is injected into the mixing duct so that the high pressure air and the fuel is uniformly mixed therein so as to produce minimal formation of pollutants when the fuel/air mixture is exhausted out the downstream end of the mixing duct into the combustor and ignited. In addition, the mixing duct of the mixer includes slots, preferably with flares associated therewith, at its downstream end which modify the shape and direction of mixing eddies emanating therefrom.

摘要： An improved technique for the active control of various combustion devices. This improved technique employs a flame kernel pulse actuator which produces periodic flame kernels by a spark ignition of a stoichiometric air and fuel mixture upstream of the combustion chamber. The discrete flame kernels are convected in a duct of premixed fuel and air which produce discrete pressure oscillations due to the energy release as each discrete flame propagates. Because the source of the energy release is essentially a chemical reaction, the flame kernel pulse actuator is able to produce a substantial amount of energy release even at the high operating pressures which are often encountered in many operational environments. These pressure oscillations may be adjusted to suppress or augment any combustion induced pressure oscillations as well as act to modulate the mixing layer between the fuel and air, thus controlling the downstream combustion process.The flame kernel pulse actuator comprises an actuator housing, a secondary fuel injection system, and an igniter. The combination of the igniter and fuel injection system produces a plurality of discrete flame kernels which are convected downstream toward the combustion chamber. The present flame kernel pulse actuator further includes a pressure sensor which is positioned so as to measure the acoustic oscillations in the combustion chamber and a controller device which uses the output of the sensor to control the frequency, phase shift, and amplitude of the discrete flame kernels.
摘要翻译：一种用于各种燃烧装置的主动控制的改进技术。这种改进的技术采用火焰核脉冲致动器，其通过在燃烧室上游的化学计量的空气和燃料混合物的火花点火来产生周期性的火焰内核。离散的火焰内核在预混燃料和空气的管道中对流，由于每个离散的火焰传播时由于能量释放而产生离散的压力振荡。由于能量释放的来源基本上是一种化学反应，即使在许多操作环境中经常遇到的高操作压力下，火焰核脉冲致动器也能产生大量的能量释放。可以调节这些压力振荡以抑制或增加任何燃烧诱发的压力振荡，以及用于调节燃料和空气之间的混合层，从而控制下游燃烧过程。火焰核心脉冲致动器包括致动器壳体，二次燃料喷射系统和点火器。点火器和燃料喷射系统的组合产生了向下游朝向燃烧室对流的多个离散的火焰内核。目前的火焰核心脉冲致动器还包括压力传感器，其被定位成测量燃烧室中的声振荡;以及控制器装置，其使用传感器的输出来控制离散火焰的频率，相移和振幅内核
