As a result, the availability of the gas turbine is severely impaired.

  • the mobility of the cleaning device results in rapid availability of the device at different locations. It can be cleaned by changing the cover with a body different burners of different types of machines. Also, different types of burners such as pilot and diffusion burners can be cleaned. In particular, the cleaning of a pilot burner, in particular a premixed pilot burner, which has even smaller mixing nozzles than the already clogged diffusion burner can be blown out with the mobile unit. This is particularly advantageous since for pilot burners (diffused and premixed) there is currently no satisfactory solution for efficiently removing deposits from the component. By the inventive cleaning device and the method can now be dispensed with the disassembly of the burner into individual assemblies. Furthermore, new component components or manual cleaning are no longer necessary.
  • a further advantage is that by the quick and easy carrying out of the method by means of the device, a more frequent elimination of the deposits is possible, whereby now the emission limit values can be maintained much easier. Furthermore, the efficient cleaning of component sections, which can not be cleaned manually or easily (undercuts, cavities), is also favorable.
  • the device presented here and the method can be used not only on burners with premix gas channels but on any burner type, for example, burners for industrial gas turbines. By the device and the method is thus a faster and improved Cleaning possible directly on the system. If the burner is cleaned in an acid bath, in particular in a citric acid bath, it is possible to blow it out during the individual steps.
