摘要： In a burner for operating a combustor, the former consists essentially of a rotation generator (100), a transition piece following the rotation generator, and a mixing pipe following this transition piece. Transition piece and mixing pipe form the mixing section (220) of the burner and are located upstream from a combustion chamber (30). In the lower part of the mixing pipe is located a pilot burner system (300) which creates, among other things, a stabilization of the flame front, in particular in the transient load ranges, while minimizing pollutant emissions. A sensor (400) installed in the burner detects a flashback of the flame (80), whereupon the fuel quantity of this flame is at least temporarily reduced and at the same time the fuel quantity for the pilot burner is increased in such a way that the total fuel quantity and thus the turbine output remains constant. This measure prevents a destruction of the burner.

摘要： The present invention discloses a high temperature pyrometer 20 which is suitable, in particular, for temperature measurement in a gas turbine. The pyrometer comprises a flexible lightguiding measuring probe 21 with a microlens 22 resistant to high temperatures and with an optic fiber 24 composed of quartz or sapphire, said microlens and said fiber being provided with a gold sheathing 25, 26 and/or a protective capillary 27, 28. The heat radiation is evaluated in a remote detector 32 having measuring electronics 33 connected to it. The pyrometer 20 is distinguished by compactness, high temperature capability, flexibility, versatile installability and high measuring accuracy. The invention also relates to a development of the pyrometer 20 for gas turbines, to a gas turbine with a pyrometer 20 according to the invention, and to a method for monitoring a gas turbine with the aid of a pyrometer 20. Explanations are given of ways in which the measuring probe 21 can be fitted in guide blades 34, 48 and by means of which accurate temperature measurements are possible on moving and guide blades 34, 35, 48, 49 in low pressure and high pressure turbines. The operating safety and the efficiency of gas turbines can thereby be increased.

摘要： A proximity sensor, in particular a proximity switch is described. A component that pertains to a system variable and is independent from the material of a trigger or target is elected and transformed into a non-periodic signal that depends upon the distance of the trigger. The trigger of a proximity sensor can thus be exchanged randomly without requiring subsequent adjustments. The impedance of an oscillation circuit which pertains to the proximity sensor, the impedance of an oscillation circuit coil, the amplitude of the oscillation circuit signal or a voltage divider ratio between the oscillation circuit and the additional resistance can be used s system variables for instance.
