    摘要: A burner system with staged fuel injection includes at least one burner with a mixing zone. A combustion chamber is disposed downstream of the mixing zone and a first fuel introduction device is provided upstream of the mixing zone. Furthermore, a second fuel introduction device for the direct injection of fuel into the combustion chamber, is disposed downstream of the mixing zone. In addition, at least one sensor for determining combustion parameters is connected to a control device. The control device is designed to control the second fuel introduction device as a function of the parameters determined by the sensors.

    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: The burner of a gas turbine includes two or more part cone shells arranged offset with respect to one another and defining a cone shaped chamber with longitudinal tangential slots for feeding air therein. A lance carrying a liquid fuel nozzle arranged centrally in the cone shaped chamber is also provided. A portion of the nozzle facing the cone shaped chamber is divergent in shape. A diffuser angle (α) between the wall of the nozzle and a longitudinal axis of the cone shaped chamber is less than 5°. A diverging portion of the nozzle has a diffuser length to nozzle diameter ratio comprised between 2-6. The nozzle diameter is the smaller diameter of the diverging portion.

    摘要: A premix burner has a swirl generator and two perforated through flow elements are arranged at a defined distance from one another in the inflow region for the combustion air. The through flow elements are preferably arranged in such a way that substantially the entire combustion airstream has to flow through the through flow elements. The degree of perforation of the through flow elements and the distance between these elements are preferably adapted to one another in such a way that a reflection free condition for combustion pulsation frequencies which may be expected is present at the exit from the burner into the combustion chamber.

    摘要: In the case of swirl-stabilized premix burners (1), an axial mass flow distribution of the fuel introduced which has especially favorable values with respect to characteristics such as NOx emission and maximum amplitudes of pulsations occurring is used. For this purpose, Pareto solutions are determined with respect to the said characteristics, in that a distributing device (5) with control valves is represented by a tree structure with distributing parameters, and values for the distributing parameters on the basis of which the distributing device (5) is set by means of a control unit (10) are iteratively generated in a data-processing system (9) by an evolutionary algorithm. On the basis of the values determined by a measuring unit (11), solutions which are especially favorable with respect to the characteristics mentioned, espectially Pareto-optimal, are selected. The distributing devices or the premix burners of the burner system are then formed in a way corresponding to such a solution.

    摘要: A method can protect a gas turbine engine (10), which includes a compressor (11), a combustor (13), and a turbine (12), against high dynamical process values, especially in combustor/flame pulsations. Effective protection against high dynamical process values, especially in combustor/flame pulsations, can be achieved by: a) measuring the pulsations of the combustor (13) with a suitable sensor (18), b) dividing the frequency spectrum of the measured pulsation signal up into pre-defined band pass sections, c) computing the rms (root mean square) of the signal for each band, d) weighting the computed frequency/frequency band rms with predetermined weighting factors, e) cumulating the weighted frequency/frequency band rms values to get a Pulsation Limit Criterion (PLC) value, f) comparing the PLC value with at least one reference value (23), and g) operating the gas turbine engine (10) according to the result of the comparison.
