摘要： In an annular combustion chamber for a gas turbine, a combustion-chamber dome (14) is arranged upstream of an air-cooled combustion chamber (10). A first portion of an air flow (46) which comes from the compressor is admixed as combustion air to the combustion operation and cooling ducts (22; 24) feed a second portion of the air flow (46) coming from the compressor as cooling air into the combustion chamber (10). In this case, the cooling ducts (22; 24), which run at least in sections along the combustion chamber (10), have an entry (23; 25) into the combustion-chamber dome (14). The cooling ducts (22; 24) are designed for damping combustion-chamber oscillations in such a way that the acoustic impedance at the entry (23; 25) of the cooling ducts (22; 24) into the combustion-chamber dome (14) is minimized.

Within the reception unit, at least one hollow duct is provided, with at least one duct orifice facing away from the swirl space and with a duct longitudinal extent which runs essentially parallel to the burner axis.

摘要： In a burner (1) having an interior space (22) surrounded by at least one shell (8, 9) in which burner (1) fuel is injected through fuel nozzles (6) arranged at the burner shells (8, 9) into a combustion air stream (23) flowing within the interior space (22), the fuel/air mix which is formed flows to a flame front (3) in a combustion chamber (2) within a delay time (τ), where it is ignited, the formation of combustion-driven thermoacoustic oscillations is avoided by virtue of the fact that means (24), which allow fuel to be injected into the combustion air stream (23) via at least two fuel injection holes (25) distributed over the length of the means (24) are arranged so as to project from the burner base (27) into the interior space (22) substantially in the direction of the combustion chamber (2), so that the delay time (τ) between injection of the fuel and its combustion at the flame front (3) corresponds to a distribution (12) which avoids combustion-driven oscillations in premix operation.

摘要： A reheat combustion system for a gas turbine comprises a mixing tube adapted to be fed by products of a primary combustion zone of the gas turbine and by fuel injected by a lance; a combustion chamber bed by the said mixing tube; and at least one perforated acoustic screen. The or each said acoustic screen is provided inside the mixing tube or the combustion chamber, at a position where it faces, but is spaced from, a perforated wall thereof. In use, the perforated wall experiences impingement cooling as it admits air into the combustion system for onward passage through the perforations of the said acoustic screen, and the acoustic screen damps acoustic pulsations in the mixing tube and combustion chamber.

摘要： A sensor 11 detects the acoustic pressure at a first location in a combustion chamber 7 of a test rig 1 and produces an input signal which is a function of the acoustic pressure. A controller 13 receives the input signal and produces an output signal which is a function of the input signal. An acoustic actuator (16-18) receives the output signal and introduces into the combustion chamber 7 at a second location an acoustic pressure which is a function of the output signal. The acoustic actuator may comprise a fuel injector 18 or a loudspeaker. By using an appropriate control algorithm, acoustic boundary conditions corresponding to a particular gas turbine combustion chamber may be produced, at least in a certain frequency range,

摘要： Relating to a model-based active control system for a gas turbine, a method for obtaining the data that are used for deriving an active closed loop controller for the gas turbine includes splitting the combustion system into a number of submodels. The measurement of some submodels is achieved by system identification on a single burner test facility. Other submodels are then determined by using known acoustic models. The different submodels are subsequently combined to form an acoustic network model that is subsequently used to develop a closed loop controller.
