Definitions

  • the invention relates to a method and a device for the detection of impurities in turbine components a turbine, in particular a gas turbine for generating of electrical energy.
  • a turbine for generating electrical energy In a turbine for generating electrical energy is the energy contained in a working medium is converted into Rotational energy of the turbine, so that a coupled to the turbine Generator is powered and electric power provides.
  • Hot gas usually generated in a combustion chamber, wherein as fuel for the burner, for example heavy fuel oil or Naphtha can be used.
  • the hot gas is supplied to the turbine blades of the turbine and thereby generates a rotation of the turbine blade ring.
  • All turbine components which come into contact with the hot gas are at risk of polluting, since at contact of the contaminated hot gas with the turbine components at least a portion of the dirt particles deposited on the turbine components. Particularly affected are the turbine blades.
  • the impurities usually form undesirable deposits on the affected turbine components, the used Fuel, the ambient conditions or the operating mode of Turbine affects how strong and / or how quickly these deposits form.
  • the coverings need to be cleaned by cleaning the affected turbine components be removed.
  • the visual inspection may, for example, reveal that a cleaning actually not yet necessary or that on the other hand maybe even damage to turbine components is present.
  • the invention is therefore based on the object, an improved Method and device for detecting Indicate impurities in turbine components of a turbine, by means of which in particular a disassembly of the turbine is avoided.
  • the invention is achieved by a Method for detecting impurities in turbine components a turbine, wherein during operation of the turbine at least one current vibration characteristic at least a turbine component is determined.
  • the invention is based on the consideration that, in particular the rotating components of a turbine due to the forces acting on them perform a vibration.
  • This vibration can be more or less severe their amplitude and / or attenuation be pronounced and of a fast decaying shock up to an undamped harmonic Range vibration.
  • the vibration characteristic value during operation the turbine determined.
  • the components in a Operating turbine forces, causing the affected Components in response with a more or less strong vibration.
  • the nature of this excited vibration depends on the degree of contamination of the component. For example, as a result of changes the pollution the mass of the component. This is the result during operation adjusting vibration of this component compared to a non-contaminated component more damped and / or has a different frequency. If now such a vibration characteristic of the in operation located turbine component determined, so you can from this, deduce impurities from the turbine component and set a cleaning schedule.
  • the natural frequency shifts with one Impurities occupied component compared to a non-contaminated component.
  • this can be detected, for example be excited by the component directly or indirectly is, for example by means of a shock, and the adjusting component vibration is measured.
  • the vibration characteristic value becomes advantageous with a vibration reference value which corresponds to a corresponding, not contaminated turbine component is assigned.
  • a vibration reference value which corresponds to a corresponding, not contaminated turbine component is assigned.
  • For example can be the natural frequency of the polluted and one corresponding similar, not polluted turbine component be determined and compared with each other.
  • the turbine component a turbine blade.
  • the turbine blades are those turbine components which are in the most intensive contact during operation the hot gas. Therefore, it is expected that pads with Form impurities especially on the turbine blades and thereby the operation of the turbine is impaired. Therefore, it is particularly advantageous to have one, several or all turbine blades of the turbine in terms of their current Vibration characteristic to examine in time contaminants to be able to determine.
  • the turbine component leads Hot gas.
  • Such turbine components not only include the aforementioned Turbine blades, but also other components, which come into contact with the hot gas, such as Henfingaszu- and / or hot gas lines.
  • the invention may also include such turbine components be examined for impurities.
  • the vibration characteristic value comprises a natural frequency and / or a vibration frequency and / or a Vibration amplitude and / or a damping characteristic and / or a vibration decay behavior of the turbine component.
  • vibration characteristics can during operation or be determined during a turbine standstill. While of the establishment must be used to determine these characteristics turbine components usually not excited separately as they occur during operation as a result of they act on forces (for example, centrifugal forces and / or slight imbalances) are excited to vibrate anyway. With respect to this vibration or vibrations then the corresponding vibration characteristic determined.
  • the invention further leads to a device for detection contaminants on turbine components of a turbine, wherein at least one sensor unit for determining at least a current vibration characteristic of at least one Turbine component is provided.
  • FIG. 3 shows a device according to the invention for detecting.
  • the turbine 3 is preferably a gas turbine, whose turbine blades are driven by hot gas.
  • the turbine 3 is on a generator 5 coupled.
