Abstract: A heat shield element arrangement including a heat shield element for a heat shield arranged on a supporting structure is provided. On each of the two opposing sides running parallel to the installation grooves the heat shield element includes a continuous screw head opening which penetrates the cold side and the hot side of the heat shield element substantially vertically and through which the screw head of the respective screw is arranged to be accessible to the supporting structure, and a spring element may be arranged under the respective screw, which spring element may be extended along the hot side of the heat shield element and the parallel installation groove of the supporting structure. An outer end of the spring element is embodied as a clamping retaining hook which is provided for the purpose of engaging in the laterally recessed retaining groove of the heat shield element.

Abstract: A burner having two ignition electrodes and a bracket is provided. The bracket is arranged on the outer surface of the burner and the ignition electrodes are held, at in each case three points of their periphery, in a fixed position using the bracket. A gas turbine with the burner is also provided.

Abstract: A mobile cleaning device for cleaning parts of a burner is provided. The mobile cleaning device includes a closable pressure vessel, wherein a nozzle end of the burner is located inside the pressure vessel. An end of the burner, which is used for supplying fuel and is arranged opposite from the nozzle end, is located outside the pressure vessel. Further, a method for cleaning parts of the burner is provided.

Abstract: A method for protecting a burner from being heated excessively during the combustion of a fuel in a combustion chamber is provided. The fuel is injected through a fuel nozzle at the same time as an inert gas in the surroundings of the injected fuel is injected into the combustion chamber in such a manner that the fuel is separated spatially from an oxidizer by the inert gas until an ignitable mixture of the fuel is produced.

Abstract: A method for supporting the automation of agricultural work or service includes collecting data, further processing the collected data using context processing rules to form a context profile, selecting process information using process assignment rules and depending on the context profile, and performing agricultural work or service depending on the process information that was selected, so that it is possible to largely automate the performance of agricultural work or service.
