Definitions

  • the present invention relates to a combustion chamber for a gas turbine with the features of the preamble of claim 1.
  • the invention also relates to an associated operating method having the features of the preamble of claim 9.
  • a combustor for a gas turbine which has a burner system having a plurality of burner groups each having a plurality of burners. Furthermore, a fuel supply system is provided, which has a main line connected to a fuel source and a secondary line for each burner group, which is connected to each burner of the associated burner group and a controllable distributor valve to the main line.
  • a combustion chamber is provided, at whose entrance the burners are arranged. In the known combustion chamber, the individual burners are operable in a pilot mode and in a premix mode, wherein within a burner group all burners are always operated either in premix mode or in pilot mode. Depending on the operating mode, the burners require more or less fuel, which can be adjusted via the distributor valves. The actuation of the Distribution valves takes place in the known combustion chamber as a function of the respective load state of the combustion chamber.
  • the burners are operated as lean as possible in the nominal operating point of the combustion chamber. Due to the lean operation, the running in the combustion chamber homogeneous combustion reaction leads to relatively low temperatures. Since the formation of pollutants, in particular the formation of NO x disproportionately depends on the temperature, the low combustion temperatures lead to a reduction of pollutant emissions. On the other hand, it has been shown that a homogeneous temperature distribution in the combustion chamber promotes the formation of pressure pulsations. Thermoacoustic pressure pulsations lead to a noise pollution and can adversely affect the combustion reaction. In extreme cases, strong pressure pulsations can extinguish the flame in the combustion chamber. It has been shown that the combustion reaction is less susceptible to thermoacoustic instabilities with less lean or with rich fuel-oxidizer mixtures. In particular, rich-burning zones may stabilize adjacent zones of lean burn.
  • thermoacoustic oscillations are detected in a closed control loop and, depending on the detected oscillations, generate acoustic oscillations of a specific amplitude and phase and coupled into the combustion chamber.
  • the thermoacoustic oscillations are suppressed or reduced if, within the control loop, the amplitude of the generated acoustic oscillations is chosen to be proportional to the amplitude of the detected vibrations. In this procedure will be thus attenuates the resulting in certain operating situations thermoacoustic oscillations.
  • US6205764B1 describes an apparatus and method for suppressing thermal vibrations in a combustion chamber.
  • the invention deals with the problem of pointing out a way to improve the performance of a combustion chamber of the type mentioned, in particular, the formation of pressure pulsations and / or the emission of pollutants should be reduced.
  • the invention is based on the general idea to determine for each burner group associated values for pressure pulsations and / or pollutant emissions and to regulate their dependence on the fuel supply to the burner groups.
  • This is realized according to the invention with a sensor system which separately detects the values for the pressure pulsations and / or emissions for each burner group and makes it available to a controller which, depending on these pulsation values or emission values, activates distributor valves which control the fuel flow to the individual burner groups or actuated.
  • the control or actuation of the distributor valves takes place in such a way that the pulsation values and / or the emission values assume or fall below predetermined threshold values for each burner group.
  • the burner system can be operated during operation of the combustion chamber with regard to the lowest possible pollutant emissions and additionally or alternatively with regard to the lowest possible pressure pulsations.
  • the actuation of the distributor valves does not take place directly as a function of the pulsation values or the emission values, but indirectly by means of proportional factors which represent for the respective burner group the portion supplied to this burner group at a predetermined total fuel flow to be supplied to the combustion chamber.
  • the controller determines a share factor for each burner group and then controls the distributor valves as a function of these share factors. This procedure simplifies the handling of the distributor valves or their actuation.
  • the controller determines the proportion factors so that the total fuel flow remains constant. Thus, the control of the fuel flows for the burner groups does not affect or only slightly on the performance of the combustion chamber.
  • Fig. 1 comprises a combustion chamber 1 according to the invention of a gas turbine, not shown otherwise, a burner system 2, a fuel supply system 3 and a combustion chamber 4, which is designed annular.
  • the burner system 2 comprises a plurality of burners 5, which are arranged distributed at an inlet 6 of the combustion chamber 4 in the circumferential direction.
  • the burner system 2 also includes a plurality of burner groups A and B, each of which at least one of the burner 5 is assigned. In the embodiment of Fig. 1 two burner groups A and B are provided, each of which a plurality of burners 5 are assigned. In Fig. 1 the burners 5 of one burner group A are designated 5A, while the burners 5 of the other burner group B are 5B.
  • the fuel supply system 3 comprises a main line 7, which is connected to a fuel source 8 not shown in detail. Furthermore, the fuel supply system 3 for each burner group A, B comprises a secondary line 9, which are also designated according to their assignment to the respective burner group A, B with 9A and 9B. Accordingly, here two secondary lines 9A, 9B are provided, which are each connected to each burner 5 of the associated burner group A and B respectively. For example, the secondary lines 9 are formed directly in front of the burners 5 as ring lines. Furthermore, the secondary lines 9 are each connected via a distributor valve 10 to the main line 7. The distribution valves 10 are according to their membership in one of the burner groups A, B designated 10A and 10B.
  • the combustion chamber 1 also comprises a sensor 11, which is connected to a controller 12.
  • the sensor system 11 is designed such that it can separately record for each burner group A, B pressure pulsation values, which correlate with pressure pulsations of the respective burner group A, B occurring in the combustion chamber 4, and / or emission values with pollutant emissions, in particular with NO x emissions , the respective burner group A, B correlate.
  • the sensor system 11 is equipped with at least one pressure sensor 19 and at least one emission sensor 13.
  • the individual sensors 13, 19 are connected to the controller 12 via corresponding signal lines 14 in connection. It is clear that the sensor system 11 of each burner group A, B can also assign a plurality of pressure sensors 19 or a plurality of emission sensors 13.
  • the sensor system 11 may have a pressure sensor 19 and an emission sensor 13 separately for each individual burner 5.
  • the controller 12 is used to actuate the distribution valves 10 and is connected for this purpose with these via corresponding control lines 15.
  • the controller 12 is configured such that it can actuate the distributor valves 10 as a function of the determined pulsation values and / or as a function of the determined emission values. In accordance with the invention, this actuation takes place in such a way that the pulsation values or the emission values assume or fall below predetermined threshold values for each burner group A, B.
  • the controller 12 contains a suitable algorithm, which determines control signals for operating the distributor valves 10 that originate from the incoming pulsation values and emission values.
  • the distributor valves 10A, 10B assigned to the individual burner groups A, B are individually controlled, ie the first distributor valve 10A assigned to the first burner group A is actuated by the controller 12 as a function of the pressure pulsations or emissions occurring at the first burner group A. while the second distributor valve 10B associated with the second burner group B is actuated by the controller 12 as a function of the pulsations or emissions occurring at the second burner group B. Since the control of the distribution valves 10 also takes place in such a way that the variable responsible for the control process is varied, the controller 12 in conjunction with the sensor system 11 forms a separate and closed control loop for each burner group A, B.
  • each of these control circuits the pulsation value and / or the emission value are adjusted to predetermined threshold values as a function of a desired-actual comparison.
  • these control circuits are not independent of each other, but rather are coupled to one another by at least one boundary condition.
  • the coupling of the control circuits by the specification of a total fuel flow, the total of the combustion chamber 4 is to be supplied via all burners 5. This total fuel flow is ultimately responsible for the performance of the combustion chamber 1.
  • the power of the combustion chamber 1 can be kept substantially constant, even if their individual burner groups A, B are varied with respect to the respective burner group A, B supplied partial fuel flow.
  • the controller 12 determines a proportion factor for each burner group A, B as a function of the measured pulsation values or emission values.
  • Each share factor represents the proportion of the total fuel flow supplied to the associated burner group A, B.
  • the control of the distribution valves 10 then takes place as a function of these proportional factors and thus only indirectly as a function of the measured values for the pulsations and emissions. By using such proportional factors, the control of the distribution valves 10 is simplified.
  • burner system 2 may again have 2 burner groups A and B in another embodiment. While in the embodiment according to Fig. 1 However, the individual burners 5 are formed in one stage, the burner 5 in the variant according to Fig. 2 multi-level, designed here in two stages.
